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: Very good thermals. - I’m running five Silent Wings 4 fans in my system, three 140mm front intakes, two 140mm top intakes, and a 120mm rear exhaust. Airflow is excellent and thermals remain consistently strong even under sustained load. The fans maintain good static pressure and stay impressively quiet at higher RPMs. Build quality is solid, and PWM control works smoothly. Highly recommended for anyone aiming for strong airflow without excessive noise. Highly recommend!

## 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?**
A: The highest CFM 120mm model is the Silent Wings Pro 4 120mm PWM. To be sure you are getting the correct one, make sure the specifications page lists the RPM as 3,000.

**Q: Will this work with a 240mm AIO?**
A: Should be fine as they are designed to be placed on air coolers
just make sure that you have enough space because of size difference like width

**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?**
A: The Pro is more expensive and designed specifically for liquid cooling radiators.
