Are you wondering if it is possible to keep your PC cool without a fan? Well, thanks to developments in technology and a clever application of physics, it is.

Fans used to be an essential component for a computer to function properly, but they can fail at crucial times, forcing you to lose data and uptime due to system failure.

How does it work?

One of the basic laws of physics is that energy can neither be created nor destroyed; it can only change from one form to another. The basic cooling process in a PC involves the circulation of cool air within the components, thus slowly ejecting heat from the device through vents.

Fanless PCs, however, do not need air vents for the circulation of air. In a fanless PC, the internal components are sealed.

So how can a computer remain cool without the circulation of air? The aim of a fanless PC is to find a way to direct the thermal energy away from the processor, RAM, and other chips; all of which produce heat.

A fanless PC makes liberal use of a device called a heatsink to connect with these components and allow the heat they emit to flow through it, in order to control the direction of heat transfer. The heat absorbed by this thermal sink then dissipates into the surrounding environment. While normal fanned computers do use heatsinks, fanless computers make use of a network of several heat sinks placed all over the board, that connect to the computer’s case which is, itself, a heatsink.

Fanless PCs are set up with external power supplies, effectively removing yet another heat creating component from inside of the computers.

Benefits of Fanless Cooling

With fanless cooling, you are not going to have to deal with the dirt and dust that builds up on the internal components over time because there are no air vents.

Also, you will avoid the problem of a single component taking down the whole system when it overheats.
