Silent Wings 4 140mm PWM combines all features of a virtually inaudible with an extremely performant fan for the most demanding applications.
Silent Wings 4 140mm PWM 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 a fan that makes no compromises between virtually inaudible operation and high performance.
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.
Be it as a radiator fan or in the case: Silent Wings 4 140mm PWM always makes a good impression. The all-black design combined with the high-grade fan sticker makes the fan shine in any system. This makes
Silent Wings 4 140mm PWM a high performant and an incredibly good-looking fan.
“We are proud of our Silent Wings 4 for being the most silent fans of be quiet! Especially with their sheer performance in mind even we are still baffled about how quiet these fans are.”
Marius Sabisz, Head of BU Cooling
