Refurbished Servers

Refurbished Servers

Servers are an integral part of any network system. In simple words, a server is a computer program or a network device that processes commands from another device or program, known as the client. This is known as a client-server architecture. Broadly, the server is classified as hardware and software. A software server is any kind of application that performs operations assigned by another program. The most common example of a software server is a web server (HTTP server) that deliver webpages. Hardware server is a networking device used to ensure communication with clients, run the soft applications with ease, and provide full functionality. Indeed a hardware server requires to be powerful and robust.

Hardware servers are further classified into three categories: Rack Servers, Blade Server, and Tower Server.

Tower Server: These are stacked in an upright cabinet, resembling the tower. However, they have an advantage of cooling down easily but are very heavy, space-consuming and cable management are complicated.

Blade Server: These are chassis-based thin severs. They offer good performance but are expensive.

Rack Server: These are designed to be stacked in a rack, modular design. This is the most efficient type in terms of management and storage. These very versatile in terms of performing tasks.

KahnServers deal with refurbished Rack Serves at attractive prices. The most efficient Dell and HP Servers are available with KahnServers. They come in two options 1U and 2U. In 1U, HP DL360 series is available in both Gen 8 and Gen 9 and Dell PowerEdge series. Whereas, in 2U, HP DL380 series and Dell PowerEdge Series are available. For these servers’ cooling mechanism, these Intelligent Servers are coupled with passive heatsink. Different models are available to take care of the storage needs. 

Reasons to buy Refurbished Servers:

Saves Cost: Newly launched servers are overpriced and the refurbished ones are available at reasonable prices. Therefore, you are getting the same specifications at much affordable prices. You can go for higher specifications and even customize your purchase, which is definitely better for the long run. 

Support: On refurbished servers, you get more intense support and the maintenance charges are not that high. One can even go for extended warranty.

Energy Efficiency: Refurbished servers consume almost 20% less energy than the new ones.

Reliable: The refurbished servers are tested rigorously before being supplied to the client, hence the performance is reliable. They are also factory reset, so you are getting an almost new server at significantly less price.

Refurbished Servers

Go Green: By buying refurbished servers, you are contributing to saving the environment by reducing electronic waste. 

Since new serves are not immune to breakdowns, they can turn out to be a much expensive affair then imagined. One can opt for refurbished servers and enjoy equally good performance like a new one with great services by KahnServers.

At KahnServers we ensure all refurbished servers are tested and packed securely before dispatching from our facility. All machines come with a standard One Year RTB (Return to Base) warranty. With all these benefits of the servers, KahnServers provides you the best solution appropriate for your need without digging a hole in your pocket.

5 Key Components of a Successful Enterprise Architecture Function

One enterprise will be very different from another enterprise in how it functions and this, therefore, requires that the enterprise components for each company are carefully planned. Enterprise architecture is something that is best left to the professionals because it’s very much like an operation theatre, where only a surgeon knows how to proceed with things. Similarly, creating and managing an enterprise architecture requires a very specific kind of skill to ensure success and a smooth flow of operations.

While one company can be extremely different from another in how it operates, five general components are applicable to every company.

1. Communication for Governance

While governance may be perceived very differently in different companies, in enterprise architecture, one needs to have every team on board when it comes to decision making. Cross-functional teams communicating with each other creates an atmosphere where the error that occurs due to miscommunication and misaligned motives can be drastically reduced through proper communication.

Arranging dialogue between teams regularly with a topic that usually revolves around the problems and challenges the company may be facing is almost crucial when you plan to move ahead. Therefore, one of the most important enterprise components is governance but it is usually most helpful when everyone is heard and there is strong communication.

Moreover, an enterprise moves forward only when everyone in the enterprise architecture is communicating closely and working in coordination.

2. Natural Instinct

An enterprise architect, other than just knowing what to do, should also know how to do it. Implementation is important in an enterprise architecture when things are to move forward and it is the job of the enterprise architect to naturally have it in himself/herself to be able to do what’s needed. This instinct largely includes pragmatism and business acumen.

How an enterprise architect should function is that they should know clearly where they stand and where they want to stand in the future. But alongside this, what’s even more important is that they should also know how to get there. This is the implementation stage.

An enterprise architect’s instinct should allow them to realize where they need to be and how they will be getting there. The architect also needs to know what to leave behind because not every tiny detail can be worried upon. For instance, not everything can be perfect but not everything can be half-done, therefore, what tells an architect when to push something comes from their natural talent.

3. Getting the Big Guns on Board

One of the key enterprise components that an architect needs to ensure is that they aren’t working alone on everything, rather it’s done with a team. However, this team and should also include senior management and executives because it is these individuals with the highest amount of experience and they are generally the decision-making machines. Another reason is that most of the decisions in a company are made at the top and the implications of these decisions channel their way to the very bottom. Therefore, it is important to have an executive on-board when creating a successful enterprise architect.

4. Prioritizing Your Actions 

An enterprise architect needs to have clarity on what to do and when to do it in the sense that they shouldn’t have too much on their plate. To ensure a successful architecture for the enterprise, an architect needs to prioritize what he or she will do and when.

Attention and energy are like a constrained resource that gets thinner and thinner when distributed over more and more tasks. While every problem and every task is to be looked after, everything needs to happen in a sequence that is professionally understood to be beneficial.

5. Adding Value to the Business

Finally, a company, in general, requires individuals that can add value to the business. Only when everyone in the enterprise can contribute positively to business operations can a company perform at its fastest pace. Every individual adding value is an important enterprise component and this can be achieved when everyone begins to reach their highest capabilities of putting in the effort for outcomes and not just in vain.

Refurbished Dell vs. HP: Which Brand Server Should I Buy?

Dell and HP are the big guns when it comes to the market of computers and servers. Roughly 50% of the market of computers and servers comprises Dell and HP, which is in fact big.

When you are considering a Dell vs an HP server, you would probably have a pile of questions regarding performance and reliability. Since both brands make it big time in the market, we know that their product has got to be worth it and hence, you are definitely making a good choice by choosing among the better brands. However, the competition is cut-throat and while each has its pros, each has its cons as well.

Here we will be comparing refurbished Dell vs HP servers and which server brand is a better choice in which situation. Each factor of both the brands is compared down below.

Market Share

HP makes up around 25% of the market of servers, having the largest share in the market with their products. Dell has the number 2 spot with about half the share as that of HP but still the second-largest overall. However, market share doesn’t really give you a solid comparison so we’ll proceed to the rest of the factors.

The Hardware

It’s always the inside that tells you what a device is really worth and what it can do for you. In the case of servers, it’s the hardware components that make up the insides of a server.

When it comes to performance, Dell can manage huge amounts of workloads for longer hours whereas HP shows 20% less efficiency when it comes to performance. If you’re looking for a device that can take up some serious processing load, then Dell has your back. HP, on the other hand, has much better storage appliances and switches for easier setups.

For small to medium-sized businesses, an HP server is a big win in terms of performance, price, and maintenance whereas larger corporations can make use of Dell for workloads.


HP has made the effort to address its shortcomings and it acquires components by 3Com and Aruba which are both notable companies, to begin with, whereas Dell hasn’t quite looked into recognizable acquisitions.

Warranty and Customer Support

Although both companies offer great warranty and customer support, Dell outshines in this aspect. It has add-on options alongside user-friendly information on hardware and the warranty process is much smoother.

However, stock warranty and support are almost similar in what they comprise for both the companies.


When buying new, delivery times would be a huge factor for the comparison. This is because Dell takes up to 2 weeks in delivery but the delivered product that comes in is fully tested, assembled and ready to use. For those who aren’t tech junkies can simply plug in and use the server without having to worry about testing, configuration, and assembly. HP, on the other hand, delivers within 1 to 2 days but the product that comes in needs to be assembled and tested in the lab of your IT department.

However, in the case of refurbished Dell vs HP servers, delivery does not make a huge difference because both servers would be built and dispatched or simply dispatched from stock. The delivery time depends on your seller.

At Kahn Servers, we build and dispatch your product within 2 working days of order placement. 


It boils down to price when making most decisions regarding IT equipment but there is again cut-throat competition in both the manufacturers here.

Both companies provide servers ranging from low to high prices, although, to be fair, servers aren’t low priced from a relative perspective.

However, Dell tips towards a slightly less expensive side as compared to HP and this is mainly because Dell is widely used and spare parts are correspondingly also cheaper.

HP, on the other hand, provides more stability in the long run and is generally enterprise friendly when it comes to price wherever Dell would fit the needs of small-scale operations.

Kahn Servers provide refurbished Dell and HP servers at great prices and a one year RTB warranty. Moreover, we also deliver within 2 days so you have your product fully tested and verified, ready to use within 2 days of order placement.

Step by Step Guide to Build Your Own Server

Here at Kahn Servers, we allow you to build your own server using exactly the components that you need inside the device. The requirements of one business or server station could be very different from those of another and one does not have to stick with pre-built devices and simply make do. Having the flexibility of choosing your own components in the server gives you the freedom of aligning the device to your needs by 100%.

In this guide, we will be talking about how you can build a server for yourself to ensure lower costs and higher performance in a way that your requirements are fulfilled.

At Kahn Servers, we build the device for you, therefore, you do not need to worry about adding something that isn’t going to fit in.

But the question of what internal components you are going to use still remains. For this, you should be fully clear on what tasks your server is expected to perform and how much load it will be facing when in full throttle.


In order to choose the right chassis, you should know whether you require a rack mount, a tower or a blade server. These are the three main types of chassis you will find when you head out to build your own server.

Power requirement is one of the major factors that should contribute to your decision. A tower server typically operates between 300 to 800 watts whereas a rack server between 350 and 600 watts. Choosing the right server based on power requirements depends on how many hours a day you will have to keep your server running. While a tower server tips towards the cheaper side, it requires more power. Therefore, if you need your server to be running 24 hours a day, the rack server would be a better option.


A CPU is a brain behind a computer and it largely controls how efficiently your server will be functioning. Moreover, the choice of a CPU also defines what kind of motherboard and chassis you will be choosing, therefore, compatibility is a major contributing factor when making this decision.

There are two leading types of processes in the market today, being Intel and Advanced Micro Devices (ADM). Intel CPUs include Pentium, Core, and Celeron whereas ADM includes Sempron, Athlon, and Phenom.

Both are competitive in performance but choosing the right CPU depends on your chassis, workload, and heat management method.


Choosing the right kind of RAM depends on whether you require a DDR3 or a DDR4. Moreover, an 8GB RAM works great in most cases and a 16GB RAM becomes an overkill but there are instances where the load on your server requires a 16GB RAM or maybe even more.

Hard Drive

A server stores programs and user data and depending on many clients the server is connected to and what amount of data is moving about the network, you need to choose a hard drive accordingly. Reliability, performance and response time are the major contributing factors and finally, you need to check if it is compatible with your chassis and motherboard.


The motherboard your server will need primarily depends on which hard drive, RAM type, and CPU you have chosen. Once everything else has been decided, choosing the motherboard is a pretty straight forward job, you just need to find compatibility.

Network Card

The type of network card you’ll be using depends on the type of network in your area of use. Most commonly you find ethernet, FDDI and token ring cards. Ethernet cards are more widely used for the compatibility. USB interfaces are also available but not entirely recommended for server stations.

The network card you’ll be using also mainly depends on the communication speed your network service offers.

Raid Controller

A raid controller is the component that controls the intersection of the server and storage. You will be choosing between an internal or an external RAID controller. Your decision would be based on whether you need a RAID controller with memory, cache memory, active support and software development and what performance level you require.


A PSU controls the power supply to your server and your decision on which PSU to use would mainly depend on what is the power outlet in your area and what wattage your servers requires when functioning.

We build your devices at Kahn Servers and test them for errors before dispatch. You can therefore shop with the satisfaction that there is no margin for error, anything going wrong will be pointed out in the testing phase before the device gets to you.

DDR3 vs DDR4 RAM: Benchmark & Performance Comparison

Memory requirements for computers have gone up drastically in the last few decades. The first mainframe computer that dealt with heavy calculations had a processor and memory equivalent to around one-tenth of an iPhone. Computer RAM needed today to just read an article on the web is roughly a few gigabytes.

When deciding which computer RAM you need to install for better performance, you would generally decide between DDR3 and DDR4 type memory chips. DDR3 is the slightly older generation that served computers from 2007 onwards. They had built-in ECC memory with an extra data byte lane that corrected major and minor errors for higher reliability and it gave a higher bandwidth as well.

Then came the DDR4 computer RAM in 2014 which is much faster than the DDR3 but everything has a cost to it. This article talks about which computer RAM you should be installing that aligns perfectly with your work requirements.

Basic Differences

The DDR4 RAM comes with 280 pins whereas the DDR3 RAM comes with 240 pins. The extra pins are meant to give higher bandwidth although the difference is not immediately visible because spacing in the pins in the DDR3 is 1.0 mm whereas that in DDR4 is 0.88 mm. This implies that you can’t just plug your DDR3 out and replace it with a DDR4, the difference in the pins rehires for you to make sufficient adjustments.

Moreover, a single DDR3 chip can offer a maximum of 8GB of space, this means that if you have two slots that are compatible with DDR3, you can get a maximum of 16GB in RAM. However, the DDR4 RAM does not have any limit and you can get abnormally large amounts of storage in just one chip.

One of the biggest advantages that a DDR4 has over a DDR3 is that the DDR4 runs on just 1.2V whereas the DDR3 runs on 1.5V. This may not seem like a significant difference but imagine a server station that houses hundreds of servers or maybe more and this supposedly subtle difference can make a huge difference in the electricity consumption of the station.


The DDR3 RAM gives a transfer rate between 0.8 GT/s and 2 GT/s. On the other hand, the transfer rate of a DDR4 RAM is between 2.3 GT/s and 4 GT/s. However, the significant increase in the transfer rate gives the DDR4 a higher latency, so while the DDR3 takes roughly 13.75 ns to initiate reading, the DDR4 takes 14.25 ns.

This may not seem like a significant difference when you are doing tasks like editing a document but it makes a huge difference when you’re rendering videos or compiling programs.


As said earlier, the number of pins in the DDR3 and the DDR4 RAM is different, therefore the two computer RAMs are not backward compatible. This means that you can’t use a DDR4 RAM on a computer motherboard that has slots for the DDR3. Moreover, you can’t use DDR3 and DDR4 RAMs together on one motherboard, you have to decide between one.

Compatibility is closely related to pricing as well because if you are planning an upgrade from the DDR3 to the DDR4, then you will have to purchase more than just a RAM module.


If you are planning to upgrade from the DDR3 to the DDR4, then it wouldn’t pay off as much if you are simply going to replace the RAM unless you are upgrading the rest of the hardware in your computer as well.

However, if you are deciding to create a new server or a computer, then you should definitely go for the DDR4. This is mainly because the price difference between both the chips isn’t extremely drastic, with a difference of a few dollars, you can get a DDR4 counterpart of a DDR3 computer RAM. Moreover, the DDR4 requires less energy and the design is likely to fit future needs as well, it is definitely the option to pick.

What Do We Suggest?

Here at Kahn Servers, we offer DDR3 and DDR4 RAMs under a wide range of memory modules and you can pick one to fit your needs. But if you are just planning on getting a few extra gigs in your computer, then you do not have to replace entire hardware for just the RAM, the DDR3 would work perfectly fine.

6 Reasons to Buy Refurbished Servers & Hardware

IT companies and businesses often need to change servers and hardware to keep up with the times and their requirements. When heading out to buy IT equipment, you take into account several things such as what tasks need to b performed, how much computational power you require and what you can and cannot afford.

When you buy a new server, you take into account the manufacturer (the brand of the server), the retailer and your configuration, but when you buy refurbished servers, there are many more factors that come into play.

These factors include the quality of the product, how much you can trust the seller and whether the seller has any certifications in refurbishing servers or not. Even if everything works fine, you would be skeptical about purchasing refurbished servers.

However, this article talks about a few reasons why you should buy refurbished servers and how it can be a better investment.

1. Get More for Less

When you buy a new server, everything inside it is new and straight out of the box and therefore, you are paying a higher price. Moreover, you are also limited to what a manufacturer can offer and there isn’t much room for customization.

However, if you need to upgrade your IT corner and have a limited budget but you also want better performance, you can always buy refurbished servers. This pays off because, for the same price or maybe even lower than that of a new server, you can get much higher specs and performance in a refurbished server. Moreover, a refurbished server allows for a great deal of customization. You can choose each product individually and build your device.

At  Kahn Servers, we allow customers to build their servers by choosing each component individually through an extremely easy to use interface. Moreover, we offer a one year warranty along with the guarantee that we test and verify each product thoroughly before dispatching it.

2. Go Green

Electronic waste is a big problem and refurbishing companies are audited annually to ensure that their electronic waste is not going into landfills. These companies need a channel to make good use of electronics that can’t be sold as new products.

When you buy a refurbished server, you are making use of a product that has the ability to deliver the required performance but would have otherwise ended up in waste. You also help refurbishing companies productively get rid of the heaps of electronic waste that would otherwise just pile up if nobody bought it.

3. Smaller Lead Times

It feels great when you order something online and it’s shipped within a day or two. When buying refurbished servers, they are usually shipped on the same day and in case of customizations, they are still shipped in 2 to 3 days. New products, on the other hand, take much longer and the lead time can be agonizing.

At  Kahn Servers, we build and dispatch your product within as little as 2 working days.

4. Easier Returns and Cheaper Maintenance

When you buy a new product and want to return it, it takes a long time for the return to get approved and apart from just that, the process itself is a hassle. Refurbished servers, on the other hand, are easily returned to the retailer and the refunds can happen quickly.

Moreover, the spare parts of refurbished servers are both cheaper and readily available. Newer products require that their spare parts are purchased from the manufacturer which can take a while whereas spare parts of older equipment are available whenever you are ready to purchase them.

5. Save Shipping

New servers come with expensive shipping and handling costs, also mainly because servers are delicate and heavy devices. However, a refurbished server may even come with free delivery in most places and other than that, since it is shipped directly without the involvement of third parties, you save largely on shipping costs.

6. Save in the Longer Run

IT equipment depreciates quickly, an iPhone comes out every year deprecating the preceding one. Therefore, it is sometimes wise to go for refurbished since newer technology is always coming in and you can simply keep upgrading your device.

5 Powerful reasons why refurbished servers offer great value

If you’ve had to upgrade the servers at work at least once or twice, you would know how expensive the whole ordeal can be. Running businesses is all about cutting costs and making do with as little as possible while not compromising on the outcome. But how can you cut costs on servers but still get as much out of them as required? One of the most common ways around this is to make use of refurbished servers.

So what justifies the use of refurbished servers given that they were abandoned by other firms or software houses? Moreover, is the lower cost worth the benefit in terms of performance and reliability?

Here are some of the reasons why refurbished servers can offer great value and are a good investment.

1. Not All Refurbished Servers Are the Same

A server can be simply refurbished and then a server can be expertly refurbished. The difference here is that for someone who makes a living from refurbishing servers and knows what he/she is doing will never sell you something that would turn out to be a bad investment. Such experts would also warranty their product for buyer confidence.

Kahn Servers offers expertly refurbished servers that have been put a great deal of effort to ensure their performance and reliability. Moreover, we offer a one year RTB warranty so you can shop with peace.

2. They Help You Save Big Time

Saving money from wherever possible is a key factor when running businesses. You have better options to scale your business when you have money left behind to do that and you can save big time on your servers.

Refurbished servers come with a price tag that may just be a fraction of the price of a new device. Moreover, you can also make use of refurbished RAM and other components to bring your costs further down. It makes a huge difference in your costs when you go for refurbished instead of new and therefore, you save up for use in other places.

Not just that, when you buy refurbished, you can also go for cheaper brands that function just as well as more expensive brands but you save some serious bucks for the same performance.

3. Great Performance

A server works only as well as it has been configured for use. Whether you are buying a new server of a refurbished one, you will need to configure it with the right kind of components and equipment to optimize its performance. This configuration depends on the kind of work your server should be capable of handling. A refurbished server that has been configured just right will allow you to perform tasks like virtual machine hosting, 3D rendering, or domain rendering.

Sometimes, a refurbished server may even function better than a new server because of the components and configuration that have been applied. This implies that you can get the best out of a refurbished server if you can simply get it to be configured just right for your requirements.

Here at  Kahn Servers, we offer expert opinions on what to use on your server and how to configure it given the job that needs to get done.

4. Align with Your Requirements 

Refurbished servers have the advantage that you can customize them at a later time after the installation as well instead of heading out to buy a new server. Refurbished servers are also initially customized and therefore, there is more room for replacements and upgrades, should your server ever malfunction or outdate. In the longer run, you end up saving even more than that in the beginning because you can make do with a refurbished server for a long time by upgrading it timely. Upgrading it for certain parts allows for it to meet your technical and performance needs while not getting too pricey.

5. Reliability

While it’s understandable that refurbished servers may be offering lower reliability as compared to new servers, you can still work your way to high reliability. Look for servers that have a replacement or a money-back warranty. In the case of servers that have been configured, you get a manufacturer’s warranty for new components and all other components should be carefully and individually be tested before installation.

At  Kahn Servers, we carry out elaborate tests to ensure the optimum performance of all parts and products before we dispatch them. This comes with a one year warranty to reduce the margin of faulty equipment in your hands.

7 Important Facts About Dell Server Components

Servers are devices that connect with multiple users, programs and clients in an environment where they are required to take requests and solve them. A server is usually a device that is required to function 24 hours at a stretch and 7 days a week, this means that it is not normal to be shut down for maintenance very often. When choosing a server for your requirements, it is therefore important for you to choose something that you know will function through thick and thin.

Here at  Kahn Servers, we build dell servers with some of the most qualitative dell server components to ensure reliability.

Dell servers have made it big time in the market while being an excellent all-rounder since they meet requirements and processing loads of all kinds in all kinds of environments. Here are some facts about Dell server components that we bet you never knew.

1. Complete Coverage

2. Awards for Dell Servers

Throughout 2002, Dell received several awards for its PowerEdge line of servers for excellent performance and value offered in terms of price. An unreliable server stands in your way of providing trouble-free connections to your clients and users. Choosing the right kind of device will help you grow and nothing speaks better for a device than the word of someone who has previously used it.

3. Dell Components Reliability

The IT Manager at a large-scaled media and newsgroup went on to explain that Dell had not broken down for a single minute ever since their servers had been set up. This was due to the sturdy components that could make it through thick and thin with ease.

4. Server and Components Availability

It can be agonizing to not find a suitable replacement or upgrading hardware for your previously installed server. However, Dell has been known to offer a 99.99% availability of products and hardware over multiple generations. Therefore, no matter what generation and device you are using, you are always covered by Dell for components and replacements along with upgrades whenever, and wherever.

5. Excellent On-Going Support

Dell claims to offer support to its clients that is as good as the support that their clients offer to their clients. This is one highly effective method of getting across the fact that Dell understands your needs and aligns with the business ethics that you require for yourself.

6. Dell’s Automated Services

When it comes to servers and components, Dell provides automated tools and services that help you stay on top of your IT while keeping things as simple as they can get. You do not have to get into the nitty-gritty details of everything while setting up and getting around with new components. Sever management, set up and maintenance cannot get easier than that which Dell provides.

Here at  Kahn Servers, we go ahead by one more step to make things easier for you. We do not want our customers to get into the tiny detail of the work, therefore we simply do all the little work the involves building and replacing parts and components on refurbished servers. You on the other hand simply have to connect and use. It can’t get easier than this.

7. Remote Maintenance

An additional service that Dell offers to its clients is the maintenance of servers that can be done remotely. In a world where one just cannot stay and cater to business from one place, it is important to b moving around a lot. However, not being physically available may increase your chances of prolonged time outs in case of a breakdown when you can’t be there to fix it. However, Dell servers allow you to maintain your server without actually having to physically be there for the work.

5 Myths About Refurbished Custom Server

Servers are processing machines that are required by businesses and setups where multiple users, clients, and programs need to connect and share data. In most cases, a server runs for long periods without being shut down. And in such cases, a server shutting down or malfunctioning can cause problems that go a long way for the businesses.

Servers can be expensive devices and businesses need to make a rewarding decision when deciding which server to purchase. And given the delicacy involved with the performance and functioning of a server, there is little margin for wrong decisions. Therefore, many businesses prefer to spend large amounts of money on newer servers.

What goes overlooked is the fact that refurbished servers, also often known as rectified servers can solve the problem as well. However, there are certain myths about custom refurbished servers that keep businesses from saving loads of money that could be used elsewhere. These have been explained below.

Refurbished Servers Were Defective Once

A server may simply be sold under the label of refurbished because it was overstocked and the batch would not sell out completely before a newer version becomes available. Moreover, a device that incurred minor damage on the exterior while shipping or packaging would also be sold as refurbished because it can’t be sold as new anymore.

Some servers that were used as demo devices in stores are also later sold as refurbished products when a newer version becomes available. Other cases include a situation where a customer purchases a device but returns it because it does not meet their requirements, the server would then be re-packaged and sold as refurbished.

Therefore, you can understand how all custom refurbished servers were not defective at one point, they were simply unfit to be sold at the price of a new device. Such a device would work just fine for you, in fact, it will work like new because it is essentially new.

Refurbished Servers Don’t Come With Warranty

Some refurbished devices have a manufacturer’s guarantee and some retailers also offer it. Here at Kahn Servers, we offer a one year RTB warranty with all our refurbished products.

Other than custom refurbished servers, our warranty is also extended to heatsinks, hard drives, and other products, etc.

Servers Are Only Meant for Corporate Use

This is absolutely not true, as long as a server fits in your space and gets the job done pertaining to your processing needs, you can benefit from a server in any environment.

Moreover, it is common for software houses and enterprises filled refurbished hardware largely including servers. Refurbished servers allow such corporates to save big time when it comes to hanging costs. Moreover, in any other non-corporate environment, you can make use of refurbished servers to fit your needs in minimum possible expenses.

All Refurbished Servers are the Same

While refurbished servers have been repackaged, it does not imply that all refurbished servers are the same in terms of functionality. This is because one server may have had major equipment replacement and that may not have been carried out by professionals. Moreover, a refurbished server may also not be tested and verified before being sold. However, at Kahn Servers, we test and verify each server and also ensure that our customers do not get a defected product under any case.

Therefore, all refurbished servers are not the same and you need to be careful about what you and where you buy it from. Moreover, always look for a warranty because you should have some kind of security when it comes to buying refurbished servers. We offer a one year RTB warranty to our customers on all servers for our customers to shop with confidence.

Refurbished Servers Are Cheap

While it’s true that most refurbished products come under a much cheaper price tag, this isn’t always true. Some refurbished servers from newer generations may only have a price difference of 5% to 10% from the retail price. The reason is that some servers are only sold as refurbished because they couldn’t be sold as new, but there is nothing wrong with such devices. Therefore, you should always check the retail price and see whether the refurbished device is worth it or not.

Here at Kahn Servers, we offer some of the lowest prices for high quality custom refurbished servers for our customers.

What is a Heatsink Fan, and How Do You Pick a Good One?

A heatsink fan is also often simply called a heatsink. A heatsink is a thermally conductive device that is designed to keep your CPU cool. When your CPU is being used, it heats up. Depending on how much the CPU is at work, it can go from medium hot to very hot, to the point where it can fry itself. Therefore, it should make sense as to why a CPU requires a heatsink fan for efficient working.

A heatsink spreads the heat produced by a CPU over a larger area and hence keeps the CPU itself cooler. This happens because the heatsink is made of a thermally absorbent material that effectively absorbs the heat produced by the CPU. This thermal energy is then dissipated over a larger area and hence reduced in magnitude, therefore keeping the CPU cool.

Some heatsinks are combined with a fan and this is referred to as an active heatsink. An active heatsink will cool down the device efficiently but may also be louder. Some heatsinks and fans also make use of liquids to cool down processors.

How Does a Heatsink Fan Work?

As said earlier, a heatsink has an adequate amount of surface area that is in contact with the processor, this surface area is highly thermally absorbent. It is designed to transfer heat from the processor to the body of the heatsink itself. A glue, that is better known as a heatsink paste, is applied to connect the two surfaces to avoid any air bubbles or impeding voids between the contact area of the heatsink and processor.

When the CPU gets hot, the heat transfers from the CPU to the heatsink which significantly cools down the CPU. Fans are used to cool down the surface of the heatsink over which the heat from the processor is spread.

Some heat sinks that use liquids are one step more effective in cooling down the processor. Inside such heatsinks, water is stored under a partial vacuum. When the processor is moderately warm, the water in the heatsink evaporates and rises to a higher level where it is cooled down and condensed. This may be done with the use of a fan.

How to Pick a Good Heatsink and Fan at Kahn Servers?

When you go out there looking for a good heatsink and fan, chances are that you don’t even know where to begin.

When you build your server at Kahn Servers, you may be wondering which heatsink and fan you require, if any, for efficient working of your device. Of course, we are there to help you out in such a situation, but if you are into the tech then you may also want to know how to pick a heatsink for yourself.

Stock heatsinks are usually the best ones out there because they are made specifically for the device. For efficient use, you may want to stick to your stock heatsinks and fans. However, stock heatsinks are also often louder.

Moreover, in the situation that you build your device, you don’t have a stock heatsink. In this case, you need to know that heatsinks and fans should effectively keep the temperature of your device between 32 and 43-degree centigrades. While most motherboards shut down if the temperature goes beyond 80-degree centigrade, you should ensure the care of your device against heating through the use of a good heatsink.

Apart from just cooling, you may also choose a heatsink that works quietly along with keeping your device cool.
