Fan Corsair RS140 14 cm White 330-1700 RPM

The Corsair RS140 is a 140 mm case fan that connects directly to the motherboard via a single 4-pin PWM connector, allowing daisy-chaining of multiple RS series fans without additional hubs or excessive cables. Designed for balanced airflow and static pressure, the RS140 is suitable for use as a case fan or on radiators, offering a variable speed range from 330 to 1700 RPM and a compact white finish to match many builds.

Advantages

Engineered blade shape and optimized housing maximize airflow efficiency while maintaining effective static pressure for radiator use. Corsair AirGuide stator vanes focus exhaust airflow to improve coverage of radiator fins and heat dissipation. The magnetic dome bearing reduces friction and mechanical noise, increasing longevity and helping the fan deliver high performance with a low acoustic footprint. PWM control and support for Zero RPM mode enable precise speed regulation and the ability to stop the fan at low loads to eliminate noise.

Suitable for

• Case cooling in desktop PC builds
• Radiator cooling for liquid CPU/GPU cooling loops
• Systems requiring quiet operation with occasional high airflow

How to use

Install the RS140 into your case or radiator frame using the appropriate mounting screws for a 140 mm fan. Connect the fan chain to a motherboard 4-pin PWM header—daisy-chain subsequent RS series fans to the same header if needed. Use the motherboard fan control or BIOS to configure PWM curves and enable Zero RPM mode where supported to control noise and performance dynamically.

Recommendations

For optimal cooling performance, place the RS140 so its airflow direction aligns with your case airflow strategy (intake or exhaust) and ensure adequate clearance around radiator fins. Configure PWM curves in your motherboard firmware to balance idle silence and peak cooling when required.
