CORSAIR RS140 II ARGB White 140mm ARGB PWM Fan - Single Pack - CO-9051074-WW

CORSAIR RS140 II ARGB White 140mm ARGB PWM Fan - Single Pack - CO-9051074-WW

The CORSAIR RS140 II ARGB is a 140mm PWM cooling fan designed to balance strong airflow with low noise across case and radiator duty. Addressable RGB lighting synchronises through iCUE with the rest of your Corsair hardware. PWM control lets the motherboard adjust speed automatically to match system temperature.

Airflow and Acoustics

The 140mm 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.

Addressable RGB Lighting

Addressable RGB allows individual LEDs to display different colours at once, producing flowing rainbow and wave effects rather than a single static shade. iCUE synchronises that lighting with your other Corsair devices so the whole build responds together. The white frame reflects the lighting and makes colours appear noticeably brighter.
