Silent Wings 4 140mm PWM high-speed White combines all features of a virtually inaudible with an extremely performant fan for the most demanding applications.

NO COMPROMISE SILENCE AND PERFORMANCE
Equally quiet and performant operation
Silent Wings 4 140mm PWM high-speed White is the fan of choice for all possible operations. Be it in a case, on radiators or heat sinks – Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 140mm PWM high-speed White a fan that makes no compromises between very quiet operation and highest performance.

OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum tolerances for maximum air pressure
Silent Wings 4 140mm PWM high-speed White 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 high-speed White allows the user to run even the most demanding applications.

DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 140mm PWM high-speed White 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 29.3dB(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 140mm PWM high-speed White.

ELEGANT LOOK
Magnificent appearance from all angles
Be it as a radiator fan or in the case: Silent Wings 4 140mm PWM high-speed White always makes a good impression. The all-white design combined with the high-grade fan sticker makes the fan shine especially in white PC builds. This makes Silent Wings 4 140mm PWM high-speed White a high performant and an incredibly good-looking fan.
