Description

No Compromise Silence and Performance
Silence Optimised Operation
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 Controller/ Advanced PWM function
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-Optimised Fan Blades
Seven fan blades with an optimised surface structure ensure virtually inaudible operation and excellent airflow.
Virtually inaudible operation
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 rubberised fan frame is equipped with funnel-shaped air inlets for excellent air circulation and extremely high air pressure, which makes the fan the perfect choice for gaming and multimedia PCs, overclocked systems and for use with radiators.
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.
