Silent Wings 4 140mm PWM High-Speed Fan

No-Compromise Silence and Performance

Silent Wings 4 140mm PWM high-speed delivers virtually inaudible operation while providing extremely high performance for demanding applications.

  • Optimized fan blades for maximum performance on radiators and heat sinks
  • Small tip clearance and funnel-shaped fan frame for extremely high air pressure
  • Very silent operation even at maximum speed
  • 6-pole fan motor and fluid-dynamic bearing for low vibration and smooth running
  • Anti-vibration mounting with push-pin and screw installation options
  • Super-long lifespan of up to 300,000 hours
  • Elegant all-black design with high-grade fan sticker
  • 5-year manufacturer warranty

Equally Quiet and Powerful

Silent Wings 4 140mm PWM high-speed is designed for versatile use in cases, on radiators, and on heat sinks. Silence-optimized fan blades and a funnel-shaped frame ensure there is no compromise between very quiet operation and top-tier performance.


Optimized for High-End Performance

The minimized distance between fan blades and frame provides:

  • Extraordinary air pressure
  • Significant increases in system performance
  • Reliable support even for the most demanding applications

Flexible Mounting Options

Two mounting options are included:

  • Pre-installed anti-vibration mounting
  • Minimizes noise-generating vibrations

  • Plastic mounting

  • Ideal for radiators and heat sinks

Both mounting types enable virtually inaudible operation at regular speeds.


6-Pole Fan Motor

The 6-pole fan motor with 3 phases is engineered for:

  • Very low power consumption
  • Reduced vibration
  • Quiet maximum operation of 29.3 dB(A)

With this technology, the fan is virtually inaudible at mid-speed.


Fluid-Dynamic Bearing (FDB)

The advanced FDB provides:

  • Super-long lifespan of up to 300,000 hours
  • Significantly reduced vibrations
  • Support for nearly inaudible operation

Elegant All-Black Design

Whether used as a radiator fan or case fan, Silent Wings 4 140mm PWM high-speed stands out visually:

  • All-black look
  • High-grade fan sticker
  • A combination of high performance and premium appearance
