CORSAIR RS120 II 120mm PWM Fan - Single Pack - CO-9051075-WW

The CORSAIR RS120 II is a 120mm PWM cooling fan designed to balance strong airflow with low noise across case and radiator duty. This non-RGB version focuses purely on airflow and acoustics at a lower price. PWM control lets the motherboard adjust speed automatically to match system temperature.

Airflow and Acoustics

The 120mm blade design is tuned to move a useful volume of air without needing high rotational speeds, which is the most effective way to keep a system cool while staying quiet. That suits both case intake and exhaust duty, and the static pressure characteristics allow it to work across radiators too. Corsair's fan engineering focuses on that airflow-to-noise balance rather than chasing headline RPM figures.

PWM Speed Control

The 4-pin PWM connector allows the motherboard to vary fan speed continuously according to a temperature curve, rather than the coarse voltage control used by 3-pin fans. In practice that means near-silent running while browsing or working, with speed rising smoothly only when gaming or rendering pushes temperatures up. Corsair fans can also be managed through iCUE for finer control alongside the rest of your hardware.

Clean, Understated Finish

Without RGB the fan costs noticeably less while delivering the same airflow and acoustic performance, which makes it a sensible choice for exhaust positions or builds where lighting is not the priority. The understated black finish blends into any chassis. It pairs perfectly with lit fans elsewhere in the build where the lighting is actually visible.
