Be quiet! Silent Wings 4 high-speed 140mm PWM
Be quiet! Silent Wings 4 high-speed 140mm PWM
The Be quiet! Silent Wings 4 high-speed 140mm PWM fan achieves outstanding air pressure thanks to its optimised fan blades and the minimised gap between the blades and the fan frame. This technology, combined with a funnel-shaped air outlet, ensures maximum performance while maintaining quiet operation. The fan uses a 6-pole motor and a fluid-dynamic bearing, ensuring smooth and silent operation. It offers a long lifespan of up to 300000 hours.
Key features of the Be quiet! Silent Wings 4 high-speed 140mm PWM
- Fan blades designed for maximum performance on radiators and heat sinks
- Minimised gap between the blades and the fan frame, along with a funnel-shaped outlet, creates very high air pressure
- Quiet operation even at maximum speed (noise level 29.3dB(A))
- 6-pole motor and fluid-dynamic bearing reduce vibrations and guarantee smooth operation
- Anti-vibration mountings with push pins and an option for screw mounting provide a stable installation
- Lifespan of up to 300000 hours
- Elegant all-black design
Uncompromising silence and performance
The Be quiet! Silent Wings 4 high-speed 140mm PWM fan is perfect for your PC case, radiator or heat sink. Thanks to its noise-optimised blades and funnel-shaped frame, it offers the ideal combination of high performance and exceptionally quiet operation.
Optimised for top performance
The Silent Wings 4 high-speed 140mm PWM ensures optimal air pressure, which also noticeably increases the performance of the entire system. This is achieved by reducing the distance between the fan blades and the frame. This allows the user to run even the most demanding applications. The all-black design combined with a high-quality sticker makes the fan shine in any build.
Various mounting options
The Silent Wings 4 high-speed 140mm PWM package includes two mounting options. The pre-installed anti-vibration mountings reduce noise and vibrations to a minimum. For radiators and heat sinks, the plastic mountings are a better fit. Both solutions enable virtually silent operation of the fan at normal speeds.
6-pole motor and fluid-dynamic bearing
The fan's 6-pole, 3-phase motor ensures very low power consumption, less vibration and therefore quiet operation at 29.3dB(A). Equipped with this advanced technology, the fan provides smooth operation and reduces costs. The fluid-dynamic bearing guarantees a very long fan lifespan of up to 300000 hours. It also significantly reduces vibrations and supports the virtually inaudible operation of the Silent Wings 4 high-speed 140mm PWM.
