BE QUIET! SILENT WINGS 2 140MM PWM HIGH-SPEED

• No compromise silence and performance

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

  • Optimized fan blades for the highest performance on radiators and heat sinks
  • Small tip clearance and a fan frame with funnel-shaped air outlets for extremely high air pressure
  • Very silent operation even at maximum speed
  • 6-pole fan motor and fluid-dynamic bearing for less vibration and very smooth operations
  • Anti-vibration mounting with push pins and screwed installation option
  • Super-long lifespan of up to 300,000h
  • Elegant look with high-grade fan sticker in an all-black design
  • 5-year manufacturer warranty

NO COMPROMISE SILENCE AND PERFORMANCE
Silent Wings 4 140mm PWM high-speed 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 a fan that makes no compromises between very quiet operation and highest performance.

OPTIMIZED FOR HIGH-END PERFORMANCE
Silent Wings 4 140mm PWM high-speed 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 allows the user to run even the most demanding applications.

DIFFERENT MOUNTING OPTIONS
Silent Wings 4 140mm 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
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
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.

ELEGANT LOOK
Be it as a radiator fan or in the case: Silent Wings 4 140mm PWM high-speed 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 high-speed a high performant and an incredibly good-looking fan.
