Fan Corsair RS140 ARGB 14 cm White 330-1700 RPM

The Corsair RS140 ARGB is a 140 mm computer case and radiator fan finished in white, designed for balanced airflow, static pressure and customizable ARGB lighting. It connects directly to the motherboard using a single 4‑pin PWM connector for speed control and a +5V ARGB connector for lighting, and supports major motherboard lighting suites including ASUS Aura Sync, MSI Mystic Light, ASRock RGB and Gigabyte RGB Fusion. The fan operates between 330 and 1700 RPM and is suitable for both case ventilation and radiator mounting.

Advantages

The RS140 ARGB combines optimized blade geometry, a maximized blade radius inside the frame and Corsair AirGuide stator vanes to improve airflow focus and radiator coverage. A magnetic dome bearing reduces friction and mechanical noise, increasing longevity while maintaining performance across the fan’s PWM speed range. Direct-to-motherboard connection eliminates extra fan hubs and cables and enables easy lighting control via motherboard software.

Suitable for

• Case cooling and general system ventilation
• CPU or GPU radiator mounting in liquid-cooling loops
• Builds requiring ARGB lighting synced with motherboard software

How to use

Mount the RS140 ARGB in your case or on a radiator using the standard four mounting points. Connect the 4‑pin PWM cable to a motherboard fan header to enable speed control, and plug the +5V ARGB connector into the motherboard’s addressable RGB header to control lighting. Configure fan curves and lighting effects with your motherboard’s software suite (ASUS Aura Sync, MSI Mystic Light, ASRock RGB, Gigabyte RGB Fusion) for combined performance and appearance.

Recommendations

For best cooling and noise balance, use PWM-controlled fan curves and enable Zero RPM mode at low CPU/GPU load to stop the fan when additional airflow is unnecessary. When installing on radiators, ensure proper push or pull orientation and allow unobstructed airflow through radiator fins for maximum heat dissipation.
