Corsair SP120 ELITE Computer case Fan 12 cm Black 1 pc(s) by Corsair

LOW NOISE, HIGH PERFORMANCE
Powerful PWM-controlled fan speeds from 300 RPM up to 1,300 RPM, pushing up to 45.4 CFM of air with 1.23mm-H20 of static pressure, while keeping noise to a minimum.

QUIET AS A WHISPER
The anti-vortex vanes direct airflow at your hottest components for concentrated cooling, whether used for intake or exhaust. In radiator fans AirGuide technology ensures better airflow cover on all radiator fins.

ZERO NOISE MODE
When your computer is not in use you can count on CORSAIR's Zero RPM mode to eliminate fan noise. Fans will spin only when temperatures reach the threshold you've set in CORSAIR's iCUE software with a CORSAIR COMMANDER fan controller.
