Description
The be quiet! Silent Wings 4 140mm PWM High Speed is a premium PC cooling fan designed for high performance gaming computers workstations and enthusiast PC builds. It combines strong airflow and high static pressure with the quiet operation that be quiet! fans are known for making it suitable for demanding cooling applications.
The 140mm fan features specially optimised fan blades and a reduced blade to frame clearance to generate high air pressure. This makes it suitable for use as a case fan as well as on compatible radiators and heatsinks where efficient airflow and strong cooling performance are important.
A 6 pole fan motor with three phase technology provides smooth operation with reduced vibration and low power consumption. The fluid dynamic bearing further contributes to smooth and reliable operation while offering a rated lifespan of up to 300,000 hours.
The Silent Wings 4 High Speed model can reach a maximum noise level of 29.3 dB(A), allowing it to deliver high cooling performance without excessive operating noise. The fan also uses a 4 pin PWM connection, allowing compatible motherboards and fan controllers to automatically adjust the fan speed according to system temperatures.
Two mounting solutions are included, giving you flexibility when installing the fan. The pre-installed anti-vibration mounting helps minimise vibration when used as a case fan, while the alternative plastic mounting solution is suitable for radiators and heatsinks. The all-black design also provides a clean appearance for modern gaming and performance PC builds.
