be quiet! Silent Wings 4 140mm PWM High-Speed PC Fan

The be quiet! Silent Wings 4 140mm PWM high-speed fan offers a perfect blend of quiet operation and high performance. Its design, featuring silence-optimized fan blades and a funnel-shaped frame, ensures it performs exceptionally well whether used in a PC case, on radiators, or heat sinks. This fan is engineered for demanding applications, delivering significant system performance increases through its high air pressure capabilities. The reduced distance between the fan blades and the frame further enhances its efficiency.
Included are two mounting options for versatility. The pre-installed anti-vibration mounts minimise noise, while the plastic mounts are ideal for radiators and heat sinks. Both solutions contribute to virtually inaudible operation at regular speeds. The fan utilises a 6-pole, 3-phase motor for low power consumption and reduced vibration.
