Fan Corsair RS120 12 cm White 420-2100 RPM 0.2-4.15 mmH2O

The Corsair RS120 is a 120 mm case fan with a direct-to-motherboard 4-pin PWM connection, designed to provide efficient airflow and radiator cooling for desktop PC builds. It operates between 420 and 2100 RPM and delivers static pressure in the range of 0.2–4.15 mmH2O. The fan is finished in white and is suitable for general case ventilation or mounting on radiators where balanced airflow and pressure are required.

Advantages

The fan’s direct-to-motherboard PWM chain connection reduces cable clutter by allowing multiple RS series fans to be daisy-chained and controlled from a single 4-pin connector. Blade geometry, an expanded blade radius within the housing, and Corsair AirGuide stator vanes combine to improve airflow efficiency and coverage over radiator fins. A magnetic dome bearing reduces friction and mechanical noise while extending bearing life. PWM control with Zero RPM support enables precise speed regulation and the option to stop the fan at low loads to eliminate noise.

Suitable for

• Case ventilation in mid-tower and full-tower PCs
• Radiator cooling in AIO or custom liquid-cooling loops
• Multi-fan setups where a single motherboard PWM header is preferred

How to use

Install the RS120 in the desired fan position using the provided mounting screws, aligning airflow direction according to your case or radiator configuration. Connect the fan series to a motherboard 4-pin PWM header; additional RS fans can be daisy-chained to the same connector. Configure fan curves or PWM profiles in your motherboard BIOS or fan control software to take advantage of speed control and Zero RPM behavior.

Recommendations

For radiator mounts, place the fans to ensure the AirGuide stator vanes direct airflow through the radiator fins for maximum heat dissipation. When creating multi-fan chains, verify that the combined current draw does not exceed the motherboard header’s specification and consult your motherboard manual if necessary.
