The only quiet pc is a fanless pc

Conventional PC's are cooled with several fast moving fans. The reason: This is the easiest method to dissipate heat. The more powerful the computer get, the bigger the noise development. How can you now combat this noise? The principle is simple: The passive cooling will be completely conversed which makes the fans redundant. Fanless PC's however, require a cleverly-devised cooling system to dissipate the immense heat production.

The Silentium!   as a fanless PC, will be solely cooled by natural air circulation. For passive cooling, heat-generating parts are equipped with accordingly dimensioned cooling bodies. The Power supply takes place with a specially developed fanless power supply unit. The good ventilated body and the specific mounting form of the power supply unit support the natural ventilation and keep the inner temperature of the body on a low level. The processor heat will be dissipated with the aid of a heatpipe to a large surface convector.

However, there is more to it than that: In conventional PC's hard disks are audible through humming and buzzing. This sounds have been abolished.

The hard disk is fully enclosed and therefore virtually unnoticeable: The hard disk is stored in a sound absorbing cooling-body. Vibration absorbers stop vibration and transmitting of excess sounds into the PC body.
