The be quiet! Silent Wings 4 PWM is suitable for a wide range of applications, such as radiators, heat sinks, PC cases, high-end PC systems, and the most demanding graphics applications. The optimized fan blades guarantee optimal performance on radiators and heat sinks. The small distance between the frame and the fan blades and the funnel-shaped air outlets ensure maximum air pressure. Operation is almost silent at normal speeds. The 6-pole motor offers low-vibration operation with very low power consumption. At the same time, the advanced Fluid Dynamic bearing minimizes vibration. The anti-vibration mounts with push pins are suitable for installation as a case fan. An alternative screw mount serves as a second mounting option.
