The be quiet! SILENT WINGS PRO 4 is a 120 mm PWM fan for radiators, heat sinks and PC cases. Optimised blades, a small gap between the blades and frame, and funnel-shaped air outlets support high air pressure.

Speed control and operation

Speed switch: select a medium-speed, high-speed or ultra-high-speed PWM limit, with a maximum of up to 3000 rpm.
Quiet operation: a 6-pole motor and Fluid Dynamic bearing reduce vibration and operating noise. At ordinary speeds, operation is nearly inaudible.
Mounting options: adaptable mounting for radiators, heat sinks or case use, with push-pin and screw mounting supported.

Connection and finish

The fan has a 4-pin PWM connector and a 50 cm sleeved cable. Its black finish is complemented by a high-gloss fan sticker. Operating voltage is 12 V.
