Advanced Fluid Dynamic Bearing Technology
The Silent Wings 4 features a premium Fluid Dynamic Bearing (FDB) that significantly reduces friction and wear compared to standard sleeve bearings. This technology ensures smooth, quiet operation and extends the fan’s lifespan to an impressive 300,000 hours MTBF. The bearing design also minimises vibration, contributing to the fan’s exceptionally low noise profile even at maximum speed.
PWM Control for Intelligent Cooling
Equipped with 4-pin PWM (Pulse Width Modulation) support, this fan automatically adjusts its rotational speed between 0-1100 RPM based on system temperature. This intelligent control system means the fan runs at minimal speed during light loads, producing virtually no noise, then ramps up only when your system demands maximum cooling. The 6-pole motor design ensures precise speed control and efficient power delivery across all operating speeds.
Anti-Vibration Design for Silent Operation
be quiet! has engineered this fan with anti-vibration mounting corners and optimised blade geometry to eliminate common sources of noise. The specially designed fan blades maximise airflow while minimising turbulence, and the rubberised mounting system prevents vibrations from transferring to your PC case. At just 13.6 dB under full load, this fan operates at a level comparable to a quiet library, making it ideal for noise-sensitive environments.
