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:
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
