Silent Wings 4 140mm PWM – No-Compromise Silence and Performance

The Silent Wings 4 140mm PWM fan delivers virtually inaudible operation while providing high-end cooling performance for demanding applications.

Key Features

  • No-compromise balance of silence and performance
  • Optimized fan blades for high performance on heat sinks
  • Small tip clearance & funnel-shaped frame for extremely high air pressure
  • Virtually inaudible at regular speed
  • 6-pole fan motor & fluid-dynamic bearing (FDB) for low vibration and very smooth operation
  • Two mounting options: anti-vibration push pins and screw installation
  • Super-long lifespan up to 300,000 hours
  • Elegant all-black design with high-grade fan sticker
  • 5-year manufacturer warranty

Silent Operation, Strong Cooling

Silent Wings 4 140mm PWM is designed for versatile use in cases, on radiators, or on heat sinks. Silence-optimized fan blades and a funnel-shaped fan frame enable a combination of very low noise and high performance, making it suitable for even the most demanding applications.


Optimized for High-End Performance

Minimum tolerances between the fan blades and the frame create extraordinarily high air pressure, significantly boosting system performance. The reduced distance allows the fan to handle demanding cooling scenarios with ease.


Flexible Mounting Options

Silent Wings 4 140mm PWM includes two mounting solutions:

  • Pre-installed anti-vibration mounts
    Reduce noise-generating vibrations to a minimum for quiet case operation.
  • Plastic mounts for radiators and heat sinks
    Ideal for performance-focused installations.

Both mounting options support virtually inaudible operation at regular speeds.


Advanced 6-Pole Fan Motor

The 6-pole, 3-phase fan motor offers:

  • Very low power consumption
  • Reduced vibration
  • Quiet maximum operation of 13.6 dB(A)

This state-of-the-art motor technology ensures the fan is virtually inaudible at mid-speed.


Fluid-Dynamic Bearing for Longevity

The advanced fluid-dynamic bearing (FDB) delivers:

  • Super-long lifespan of up to 300,000 hours
  • Significantly reduced vibrations
  • Support for the fan’s virtually inaudible operation

Elegant, All-Black Design

Whether used as a radiator fan or case fan, Silent Wings 4 140mm PWM enhances any build with:

  • A full all-black appearance
  • A high-grade fan sticker
    The design ensures a clean, premium look from every angle.
