The be quiet! SILENT WINGS 4 is a 140 mm radiator cooling fan with motherboard-controlled PWM speed adjustment. This black variant has a 4-pin connector and a 50 cm cable.

Airflow and quiet operation

Optimised blades, a small gap between the frame and blades, and funnel-shaped air outlets help build air pressure. At 100% PWM and 12 V, airflow is 51.3 CFM / 87.16 m³/h and noise is 13.6 dB(A).

Motor and bearing: a 6-pole motor and fluid-dynamic bearing reduce vibration.
Speed control: PWM adjustment through the motherboard.
Mounting: anti-vibration mounts with push-pins and optional screw mounting.
Service life: up to 300 000 hours at 25 °C.

Fit and connection

The fan measures 140 × 140 × 25 mm and uses a 12 V supply. Check that the mounting location accommodates these dimensions and provides a suitable 4-pin PWM connection.
