Be Quiet! Dark Rock Elite 6-Pole Fan Motor Technology 4-pin PWM CPU Cooler

VERY QUIET OPERATION

Achieves a great price-for-performance ratio

The Pure Wings 2 80mm PWM fan operates at only 19.2dB(A) even at maximum speed. The perfect choice for silent home and office PCs as well as gaming and multimedia systems.

SILENCE-OPTIMIZED FAN BLADES

For even better cooling

Thanks to its surface-optimized fan blades the airflow is enhanced, noise-generating turbulences are minimized and the air pressure is increased. This feature is the key to effective cooling. 

VARIABLE FAN SPEED FUNCTION

Varies the fan speed and noise level of the fan

Pulse Width Modulation (PWM) allows compatible 4-pin controllers - including those built into many motherboards - to intelligently vary the speed and thus the noise level of the fan. With PWM your system can ramp up the cooling when its needed, or operate in maximum quiet mode when its not.

RIFLE BEARING TECHNOLOGY

Gives the fan a very long lifespan

The Pure Wings 2 80mm PWM is the hallmark of outstanding reliability. This is achieved by its high-quality rifle bearing technology, which assures a very long lifespan of up to 80,000 hours.
