From 2008, it was decided to add products for the cooling of PCs (CPU coolers and case fans) to the be quiet!

is consistently concluded as a market leader in Germany for PC power supplies, from 2006 to their latest study in 2017.

In tune with the imperative in the brand name, a great deal of attention is paid in the development of all products in the be quiet!

In addition, case fan models were produced with and without the PWM function in mounting sizes from 80 to 140 millimeters.

For the technology it developed itself between 2009 and 2011, the company has lodged several registered designs and patents in diverse regions and countries.

These all share the aim: Reduction of noise in addition to optimizing the operation in cooling and power supply components.

One example is the "technology of aerodynamically optimized surface texture"[16] as used in other industrial applications to reduce operational noise and improve airflow.

In addition, the company has registered another invention for a "device to anchor the fan"[18] on the CPU cooler as a utility model.

The bracing against the heat sink serves to absorb the fan vibrations well and so inhibits the generation of noise.

The company also has a registered utility model for the "connector angular setting"[18] for the cables of its power supply products.

This special technology enables the setting and adjustment of the outlet cable angle, to suit the installation sites in differing PC configurations.
