be quiet! Silent Wings Pro 4 140mm PWM White fan, optimized fan blades, extraordinary high performance, Speed Switch for changing maximum PWM speed, 6-pole fan motor, fluid-dynamic bearing

J’en avais déjà 4 et que dire à part silence rime avec performance ! Franchement, ça coûte un bras même en promo, mais ça vaut le coup pour qui veut un airflow incomparable dans un silence quasi impérial. En promo à 26€, ma foi c'est à peine 1€ de plus que le prix que j'ai eu pour les 4 autres d’occase. Que demader... Seul regret, l'obligation de cet ineffable sticker dégueu sur la partie montants. Quand tu montes en air entrant dans un aqua, c'est vraiment dommage.

Would rate 10/10 if possible. Mounted to a kraken x63, keeps the coolant under 30°C and 5900x that it's mounted to under 74°C with an ambient if 22°C. Can be somewhat noisy at high speeds, but nothing a noise cancelling headset cant fix

El modelo blanco funciona, pero tiene un problema, la hélice roza contra la caja del ordenador, necesitas añadir tú arandelas de goma o algo similar para que se quede separado unos milímetros y no roce. Es un fallo de diseño bastante serio. El modelo negro es más ruidoso que el blanco.

Silencieux, performants et jolis sans RGB. Une véritable référence j'en ai quatre sur ma configuration qui est parfaitement refroidie.

I recently purchased the new be quiet! Dark Base 901 case which came with 1900 rpm silent wings 4 fans if I recall correctly. Originally I was going to get another one of those, but I saw these 2400 rpm versions on Amazon and got them instead. Firstly, they don’t seem to work with the fan headers used on the case, which sucks for me since it would set my fans to permanently 2400 rpm (LOUD). I ended up using my Corsair commander xt for the fans now and they work fine. That being said, the fan speed is also manually controlled on the fan itself, allowing you to change between low, medium, and high speeds. Overall, I think I should have gone with the 1900 rpm version but I’m satisfied with these for now.
