Optimized for High-End Performance
 
Minimum tolerances for maximum air pressure

The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM high-speed allows the user to run even the most demanding applications.
 
 
 
 
 
Different Mounting Options
 
For any purpose
 
Silent Wings 4 120mm PWM high-speed 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
 
The key for virtually inaudible operation when needed
 
6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
in mid-speed.
 
 
 
 
 
Fluid-Dynamic Bearing
 
For a sustainable operation
 
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 120mm PWM high-speed.
 
 
 
 
 
Elegant Look
