be quiet! SilentWings® 3 PWM fans stand for state-of-the-art technology, virtually inaudible operation and superior cooling. Their secret: a smooth-running 6-pole fan motor, an advanced fluid-dynamic bearing, a unique airflow-optimized fan blade design and a fan frame with funnel-shaped air inlets.


  • Great performance-to-noise ratio with the perfect balance between cooling and silence
  • 6-pole fan motor with three phases giving very low power consumption and less vibration
  • Advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours
  • Seven fan blades with optimized surface structures ensure excellent airflow
  • The rubberized fan frame is equipped with funnel-shaped air inlets producing extremely high air pressure
  • Removable anti-vibration mountings minimize the transmission of vibrations to the PC case and its components
  • Advanced high quality IC motor controller reduces electrical noise
