AABCOOLING Super Silent R4 is above all a high value execution, quiet operation and a low price. The set contains washers for silicone screws that are loaded with vibration removal. AAB fans owe their quiet operation to the modern FDB (Fluid Dynamic Bearing) bearing. An advantage of this solution is the service life of 100,000 hours, which is then longer than with plain bearings.

The PC case fan works with a stable speed of 1900 / 3200 ± 10% rotation. The airflow is even 4.25/7.35m3/h, and the noise level produced by propellers is 7.9 / 12.9 dB (A) making it the quietest in its class on the market. The installation is very easy - with the help of 4 screws, you can install the PC ventilation in a suitable place.
