Choose countryThe be quiet! SILENT WINGS PRO 4 is a white 120 mm PWM fan for radiators, heat sinks and PC cases. Custom mounting options let you adapt the installation to its intended position.
Speed control and airflow
The Speed Switch sets the maximum PWM speed to medium-speed, high-speed or ultra-high-speed, up to 3000 rpm. Optimised blades, a small gap between the blades and frame, and funnel-shaped air outlets help build air pressure.
- PWM connection: a 4-pin connector with a 50 cm sleeved cable.
- Smooth operation: a 6-pole motor and Fluid Dynamic bearing reduce vibration and operating noise.
- Mounting options: supports push-pin and screw mounting.
Operating figures
At 100% PWM and 12 V, airflow is 83.9 CFM / 142.5 m³/h, air pressure is 5.31 mm H₂O and noise is 36.9 dB(A). Operation is nearly inaudible at ordinary speeds. The white finish is complemented by a high-gloss fan sticker.
