Fan Corsair RS140 14 cm White 330-1700 RPM

The Corsair RS140 is a 140 mm case fan in white, designed for efficient cooling of computer cases and radiators. It connects directly to the motherboard using a single 4‑pin PWM connector, allowing daisy-chaining of multiple RS series fans without extra hubs or excessive cabling. The fan operates across a wide speed range (330–1700 RPM) and is engineered to balance airflow and static pressure for both case ventilation and radiator use.

Advantages

Optimized blade geometry and an enlarged usable blade radius within the housing improve airflow efficiency and static pressure performance. Angled stator vanes (Corsair AirGuide) concentrate exhaust airflow to better cover radiator fins. A magnetic dome bearing reduces friction and mechanical noise while extending the fan’s service life. PWM control with support for Zero RPM enables precise speed regulation and the option to stop the fan at low loads to eliminate noise.

Suitable for

• Case ventilation for mid-tower and full-tower systems
• Cooling radiators in liquid‑cooling loops
• Systems where reduced cable clutter is desired (direct-to-motherboard chaining)
• Builds requiring a white-colored fan for aesthetic consistency

How to use

Install the RS140 into your case or radiator mounting points using the supplied screws, aligning airflow direction according to your cooling setup. Connect the fan’s 4‑pin PWM cable to a motherboard fan header; multiple RS fans can be daisy-chained and controlled via a single header. Configure fan curves and Zero RPM behavior in your motherboard BIOS or fan-control software to match desired noise and cooling balance.

Recommendations

For best results, use the RS140 on radiator positions or intake/exhaust case locations where both airflow and static pressure are required. Set PWM curves to allow Zero RPM at low CPU/GPU loads to minimize noise, and ensure the fan is mounted securely to avoid vibration.
