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 it’s needed, or operate in maximum quiet mode when it’s not.     Rifle Bearing Technology Gives the fan a very long lifespan The Pure Wings 2 92mm 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.
