The CORSAIR SP120 ELITE 120mm Performance PWM Fan delivers PWM-controlled fan speeds from 300 RPM to 1,300 RPM for powerful cooling where your build needs it most. CORSAIR AirGuide Technology with anti-vortex vanes directs airflow across your hottest components to concentrate your cooling. With an extremely low-noise design and a durable hydraulic bearing, the SP120 ELITE spins as quietly as 24.7 dBa, while pushing up to 45.4 CFM of air with 1.23mm-H2O of static pressure, keeping the airflow up and the decibels down. Support for 0 RPM PWM signals enables the fan to stop completely, eliminating noise entirely for a quietly reliable cooling fan.
