The CORSAIR RS120 II is a 120mm PWM case fan for builders who want adjustable cooling for a PC case or radiator, with speeds from 420 to 2,100 RPM, up to 73 CFM airflow, and Zero RPM mode for quiet operation at low and moderate loads.
Recommended For
- PC builders adding a 120 mm case or radiator fan who want motherboard-controlled PWM speeds and a direct daisy-chain connection rather than a separate fan controller.
- Desktop users who want the fan to stop during low-load periods and ramp up when cooling is needed, using its Zero RPM mode and PWM control.
- Builders cooling a 120 mm radiator or directing case airflow who want a fan designed for both uses, with AirGuide vanes for more focused airflow.
- Builders choosing a subdued, non-illuminated look who prefer a black fan without RGB lighting.
