A fanless PC is appropriate wherever a silent IT infrastructure is desirable. However, this is not the only advantage of these systems. With fanless PCs you benefit from numerous positive features. In this article you will learn everything about fanless PCs and their special features.

Die Vorteile eines Fanless PC

What is a fanless PC?

The name fanless PC comes from the absence of active fans. Normally, all types of PCs have several fans. This applies to workstations and servers as well as laptops. The main task of these fans is to dissipate waste heat. The presence of one or more fans can be recognized by the typical whirring noise.

Cooling is necessary because, on the one hand, the hardware components generate a lot of heat. This primarily includes the processor, the graphics card and the power supply. On the other hand, the heat also accumulates in the system’s case. With the help of case fans, the warm air is constantly removed from the computer’s case. In total, conventional PCs often have three, four or even more fans.

A fanless PC, on the other hand, manages completely without these active fans. This is achieved by sophisticated and intelligent cooling concepts — these first transport the heat away from the processor and other components. A passive cooling concept is designed in such a way that the heat does not accumulate in the case, but is also dissipated to the outside.


Advantages of computer systems without fans

The most important advantage of a fanless PC is noise reduction. In fact, such systems without fans are completely silent when in use. This is a big plus, especially in the office and similar work areas. Concentration at work is not disturbed. Likewise, no noise will distract customers, which is an advantage in many scenarios.

There are also a number of indirect benefits. For example, silent PCs are particularly reliable. Mechanical components, such as those used in fans, are prone to failure. Especially in continuous operation, such as in servers or workstations, the fans’ bearings wear comparatively quickly out. This leads to the fans becoming even noisier.

Fans are also prone to failure. This is especially impractical for two reasons. Firstly, the affected system fails, and the PC is not available anymore until it is repaired. This is particularly inconvenient for servers or important workstation computers, which may lead to required services within the company not being able to be used, and therefore cause loss of revenue.

On the other hand, the failure of a fan can lead to further damage. Overheating threatens the failure of other computer components. For example, the motherboard, the CPU or even the power supply may fail. A small, inexpensive component like a fan then generates high consequential costs.

Here are the benefits of a fanless PC at a glance:

  • completely silent in operation
  • reduced maintenance requirement
  • flexible and robust
  • reliable thanks to the passive cooling system
  • can be used in many areas where PCs with fans are inappropriate
  • do not disturb the concentration at work
  • no wearing parts available

Possible uses for a fanless PC

Another benefit of passively cooled computers is their flexibility. Many application possibilities open up thanks to their technical features. Often, normal PCs with fans are inappropriate, inadequate or unsuitable.

This starts in areas where there is regular customer traffic. Computers that constantly make noise create a bad atmosphere. This is especially the case in restaurants, retail or even the hotel industry. A noiseless PC at the reception or cash desk is the right choice for undisturbed operation.

The same applies to areas where concentration is required. These are, for example, the office, educational institutions and also the home office. Here, normal PCs provide a constant background noise throughout the entire working day, which is annoying. On the other hand, with a PC with passive cooling, you have a system that doesn’t bother you throughout the day.

Hospitals and doctors’ offices also like to use completely silent PCs. Often a computer is needed close to patients, like for example, in the treatment room. A noiseless PC ensures that patients get the peace and quiet they need. And in addition, there is no disturbing noise from computers for the doctor.

Other areas in which you can use fanless PCs are industry, the trades and IoT applications. The high resilience of these systems is also advantageous here. Since there are no mechanical parts, passively cooled PCs can be used under difficult conditions. If the casing is closed and protected against dust penetration, you can use it directly in production areas.

The technical side of fanless PCs from Prime Computer

The silent operation of a PC is one side of the coin. The other is the performance. Of course, such a silent system must also have hardware with the corresponding performance. This guarantees professional work.

In Prime Computer’s products, silent concept and powerful hardware meet. Furthermore, you have the possibility to configure the hardware individually. This is an option for both the PrimeServer Pro and the PrimeMini. This makes it possible to design a system that offers exactly the performance range you need.

The options start with the processors. The PrimeServer Pro uses processors from the current Intel Xeon series. This is specially designed for use in servers. Depending on the performance you need, the PrimeServer Pro is available with four, eight or more processor cores.

The servers are also compatible with ECC memory. This is important for server tasks that require the highest precision. Furthermore, the PrimeServer Pro can accommodate up to six hard disks. Thus, operation in various RAID modes is also possible.

A powerful processor and sufficient RAM are also important factors for a mini PC for the home office. That’s why the PrimeMini is available with up to 32 GB of RAM.

For the future-proofing of the systems, an upgrade must be easily possible. This is guaranteed with Prime Computer’s products. Hybrid caddies allow additional hard drives to be added easily. The working memory can also be expanded subsequently without much effort.

This is how passive cooling is implemented in the Prime Computers

So ist die passive Kühlung bei den Prime Computern umgesetzt

In the various Prime Computer product series, a constant cooling concept is used. This includes all components as well as the case.

The case plays a central role in the cooling concept. It serves to dissipate heat to the environment. That’s why Prime Computer’s mini PCs and servers use housings made of aluminium. As a good conductor, this material is capable of both quickly absorbing and releasing thermal energy. Thus, the entire surface of the case emits the heat that is generated in the PC.

Since there is no need for air exchange between the interior and exterior, the all-aluminium case of Prime Computer products is completely closed. This results in another benefit. Namely, the hardware in the system is protected from dust. This extends the service life of the components. In addition, use is possible in areas where there is an increased concentration of dust, for example, in a carpenter’s workshop.

Passive cooling of the processor takes place with appropriately sized heat sinks. These also work completely passively, i.e. they don’t have a fan. The heat sinks are made of copper or aluminium, or a combination of both. This enables fast heat transport.

So-called heat pipes are also used for the heat transport of the PrimeServer Pro. These are heat exchangers in the form of tubes. They immediately conduct the heat away from the processor. The heat pipe transfers the heat to the aluminium case via a direct connection. This technology works completely silently and without a fan.


Passive cooling is reliable and powerful

In practice, passive cooling concepts prove to be absolutely reliable. Partly, users are concerned that passive cooling is not sufficient or that overheating can occur.

First of all, passive heat sinks are dimensioned so that they can easily absorb and dissipate waste heat. Modern processors also have mechanisms that prevent overheating. These include functions that automatically reduce the clock frequency. This technology is also used when the processor is not being used to capacity. On the one hand, this reduces power consumption. On the other hand, the waste heat is also reduced, which relieves the cooling system.

Last but not least, modern computers have sensors that control the temperature at important points. If a component exceeds one of the internal limits contrary to expectations, the system reduces the performance and protects the computer from damage.

Silent PCs: Good for the working atmosphere and the environment

With a fanless PC, you ensure a quiet working environment in which concentrated work is possible. Moreover, such systems also convince with their energy efficiency.

Special hardware is needed to implement a fanless concept. This generates as little waste heat as possible so that passive cooling succeeds. Such components, like the processor, are automatically particularly frugal. In addition, fans also need electricity during operation. A fanless PC, therefore, saves additional power here.

Thus, a Silent PC consumes less power than a comparable standard computer. In times of rising electricity prices and growing environmental awareness, this is an interesting factor. On the one hand, you lower the electricity costs in your company and on the other hand, you rely on Green IT. The use of environmentally friendly IT technology helps companies to achieve their own environmental goals.

Prime Computer products can be purchased through distributors, resellers and e-commerce shops.

Our smartly designed fanless mini-PCs and servers are designed with reliability, durability and efficiency in focus right from the development stage. Consequently, our clients benefit from an optimal combination of modern design and long-lasting performance.
