## Customer Reviews

### ⭐⭐⭐⭐⭐ Quiet and effective.
*by R***B on 7 July 2024*

Although it is auto speed controlled by the motherboard it is still quiet even when running at full speed.

### ⭐⭐⭐⭐⭐ Sauna fresh air supply fan!
*by A***N on 10 May 2017*

Bought this to introduce fresh air into our outdoor sauna cabin, wood burning stove type... fitted into the wall behind the chimney and halfway up.The fan and it's speed is managed through a miniature 12Vdc motor control... the fan is soooooo quiet at half speed which is all that is necessary to draw in fresh air. This incoming fresh air is heated by the rising heat from the sauna stones, giving us all the fresh (hot) we need.Air for the wood burner is of course is a vent/duct in the floor, NOT through this upper inlet vent.Great fan, quality made and perfect for this job. The fan body is ''inside" the 90mm Kingspan insulation board so is no where near the risingsteam - wouldn't last long in that! Aluminium ducting brings the fresh air through the wall... the fan motor is in the relative (outside) dry and cold atmosphere, so should last many years.

### ⭐⭐⭐⭐ The fan with no compromises
*by D***M on 23 April 2019*

I bought two 140mm PWM high-speed silent wings 3 and one 120 version with the same features. They are very easy to install and the box includes a set of standard fan screw mounts and an additional set of anti-vibration mounts which be quiet! claims they reduce vibrations inside your case which reduces noise levels. They are ridiculously quiet at around 1000 rpm but get very noisy at their max speeds - 1600 rpm for the 140mm fans and a whopping 2200rpm for the 120 fan which is the loudest at full speed.)In my opinion, they feel very high quality which comes from the design if the frame which is shaped like an inlet which be quiet! claims they produce more pressure and the fan blades have a unique design as well, which is my favourite feature on those fans. The blades have grooves that stretch along the entire surface of the fan on both sides which be quiet! claims they maximise airflow while maintaining low noise level. I personally believe these are the best fan designs or there and if not, one of the best.Overall, the be quiet! silent wings 3 are high quality fans that do not compromise on silence and performance while also having a great design, and the price is reasonable.
