Review: Excellent fan. - Below about 25% it is essentially silent, and still moves quite a lot of air. Even at 50% its still quiet. Yes, its noisy at 100%.... but all fans are, this one is not as noisy as any other fan I've ever used at any speed.
Review: Noise reducing fan that actually works. - I’m really impressed with these. Installed into a computer that is used in the lounge, keeps the noise to a minimum while still being powerful. Cools the computer adequately. Really easy to install with the help of YouTube. Definitely worth the money.

## Features

- Silent Wings 4 120mm 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 120mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance.
- Silent Wings 4 120mm 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 120mm PWM high-speed allows the user to run even the most demanding applications.
- Silent Wings 4 120mm 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 with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.
- 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 120mm PWM high-speed.

## Questions & Answers

**Q: I enjoy this brand of fan but have a need for high cfm.  which of the silent 4 120mm models yeilds the highest cfm?**

**Q: How many fans come in the box with the Pro 4? Is it just one?**
A: Just 1.

**Q: Silent wings pro 4 vs silent wings 4?**

### ⭐⭐⭐⭐⭐ Top performer
*by M***E on 20 September 2025*

I recently bought the Corsair RS120 (set of three), and they did not meet expectation (I could hear them over my noise cancelling headphones), I could tune with the fan curve, but even then they still fell below expectation. They're now boxed up in the cupboard as a backup. I already had a beQuiet CPU sink/fan and it's basically silent (actually silent, not just a marketing gimmick) so I thought I'd try the beQuiet Silent Wings 4 for my front fans. Needless to say they're pricey, but.... very very quiet - so I'm very happy. At highest RPM's you can hear them whirring, but for standard PC use and even gaming, they're silent or near silent. Even when you can hear it, the sounds is restrained, no hair-dryer here... If you value peace and quiet, these are the ones to go for.
