Choose countryThe be quiet! SILENT WINGS 4 140 mm PWM high-speed is a white cooling fan with blades optimised for radiators and heat sinks. Fan speed is controlled by the motherboard through its 4-pin PWM connection.
Airflow and operation
A small gap between the frame and blades, together with funnel-shaped air outlets, helps build air pressure. At 100% PWM and 12 V, airflow is 78.4 CFM / 133.20 m³/h and noise is 29.3 dB(A). The 6-pole motor and Fluid Dynamic Bearing reduce vibration.
Mounting and connection
- Mounting: anti-vibration mounts with push-pins or optional screw mounting.
- Dimensions: 140 x 140 x 25 mm.
- Connection: 12 V, a 4-pin PWM connector and a 50 cm cable.
- Service life: rated life expectancy of 300 000 hours at 25 °C.
