You probably know the typical noise of a computer. The monotonous whirring provides a constant background noise and can be heard in every office. But what many people don’t know: There is another way! Silent PCs are the solution. With these systems, the annoying background noise is a thing of the past.
Why Do Silent Pcs Not Produce Any Noise When in Use?
There are two factors that ensure that a silent PC makes no noise when in use. One is the absence of mechanical components. These primarily include fans. But classic hard disks also have mechanical parts that make noise during operation. The other factor is the cooling concept. Silent PCs rely on passive cooling.
Stability and Silence: Absence of Mechanical Components
Silent PCs operate without fans and other mechanical components. Traditional PCs, workstations and servers contain numerous fans. These are installed in various places in the housing. But silent PCs manage completely without them.
Every standard system has a processor fan. This applies to workstations as well as servers and most laptops. Furthermore, the vast majority of power supply units installed internally in PCs are cooled by a fan. In addition, there are often further housing fans in a system. Thus, a classic PC quickly has three, four or even more fans.
As a result, such a number of fans generates noise. Over time, the noise level of systems with fans also increases. Enclosure fans are comparatively cheap components. The bearings wear out or suffer a defect. Both lead to the fans emitting significantly more noise. Silent PCs, on the other hand, are permanently silent.
Silent PCs also use the more modern SSDs instead of classic HDDs. Unlike an HDD, an SSD is based on flash memory. They do not have any mechanical or moving components, such as write and read heads on HDDs. Accordingly, an SSD does not make any noise during operation.
By eliminating mechanical components, you benefit from more than just silence. Mechanical components are known to be vulnerable. A silent PC without moving parts is therefore also more reliable than a classic computer.
The Passive Cooling Concept: A Guarantee for Quietness
The foundation for dispensing with fans for cooling the CPU, power supply unit and enclosure is a passive cooling concept. This must be well thought out and individually designed for the system. The passive cooling concept takes over the dissipation of heat energy. To ensure that this works effectively and quickly, the entire system is consistently optimised for such passive cooling.
An important part of passive cooling is the computer enclosure. With passive cooling, the housing dissipates a large part of the heat to the environment. This is achieved through two techniques.
On the one hand, heat pipes are used in the housing. These are designed for the rapid dissipation of heat. The heat pipes connect the components where the waste heat is generated, for example the processor with the case.
On the other hand, special enclosures help to dissipate heat effectively. The housings of Prime Computer devices, for example, are made entirely of aluminium. On the one hand, this light metal is known for its good heat conductivity. Only precious metals such as silver or gold offer better properties. Thus, an all-aluminium enclosure absorbs heat well and at the same time releases it quickly into the environment.
Plus, another upside is that an all-aluminium enclosure is very light and yet robust. For these reasons, aluminium is the ideal choice for the housing of a silent PC.
