be quiet!

Silent Wings 4 140mm PWM makes for extraordinary air pressure and, therefore, significant increases in the system’s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 140mm PWM allows the user to run even the most demanding applications. Silent Wings 4 140mm PWM has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed. 6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 13.6dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed. The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings 4 140mm PWM.
