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

## Features

- The fan blades are what makes a fan. It is for this reason that the fan blades of Silent Wings Pro 4 140mm PWM White have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks.
- Silent Wings Pro 4 140mm PWM White makes for extraordinary air pressure and therefore, significantly increases the system’s performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 140mm PWM White allows the user to run even the most demanding applications.
- The speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 140mm PWM White alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds.
- 6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.8dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.
- Silent Wings Pro 4 140mm PWM White has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.
