  • 6-Pole Fan Motor - 6-pole fan motor with three phases for very low power consumption, less vibration and therefore quiet operation of max. 28.1dB(A).
  • IC Motor Control - Advanced high-quality IC motor controller reduces electrical noise. Pulse-width modulation (PWM) allows all compatible 4-pin controllers (including those built into many motherboards) to intelligently vary the speed of the fan.
  • Surface-Optimized Fan Blades - Seven fan blades with an optimized surface structure ensure virtually inaudible operation and excellent airflow.
  • Anti-Vibration Mountings - Removable anti-vibration mountings on all four edges of the fan reduce vibrations transmitted to the PC case to an absolute minimum.
  • Ingenious Fan Frame - The rubberized fan frame is equipped with funnel-shaped air inlets for excellent air circulation and extremely high air pressure, which makes the fan especially suitable for use in powerful water-cooling and air-cooling set ups.
  • Durable Fluid-Dynamic Bearing - The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours and greatly reduced operating noise.
