Fan Corsair RS140 ARGB 14 cm White 330-1700 RPM

The Corsair RS140 ARGB 14 cm White fan connects directly to the motherboard, using one 4-pin PWM connector for speed control and one +5V ARGB connector for lighting. It operates between 330 and 1700 RPM and is designed to provide efficient airflow and static pressure for case and radiator cooling while adding a white visual accent to your build.

Advantages

Direct-to-motherboard connectivity eliminates the need for additional fan hubs and extra cabling, simplifying installation and control through motherboard lighting software such as ASUS Aura Sync, MSI Mystic Light Sync, ASRock RGB, and Gigabyte RGB Fusion. The fan’s blade shape, enlarged usable blade radius within the housing, and Corsair AirGuide stator vanes combine to improve airflow focus and radiator fin coverage. A magnetic dome bearing reduces friction and mechanical noise, increasing durability while maintaining effective cooling across the fan’s PWM speed range. PWM support with Zero RPM mode enables low-noise operation by stopping the fan at low loads.

Suitable for

• Case cooling in desktop PCs
• Radiator and AIO cooling where static pressure is required
• Systems using motherboard ARGB and PWM control

Key specifications

• Type: Fan
• Diameter: 140 mm (14 cm)
• Speed range: 330–1700 RPM
• Maximum static pressure: 3.46 mmH2O
• Color: White
• Connectors: 4-pin PWM (speed) and +5V ARGB (lighting)

How to use

Mount the RS140 fan in the desired position in your case or on a radiator using standard fan screws. Connect the 4-pin PWM cable to a compatible motherboard fan header to allow speed control, and connect the +5V ARGB cable to a motherboard ARGB header for lighting control. Use your motherboard’s software suite (ASUS Aura Sync, MSI Mystic Light Sync, ASRock RGB, Gigabyte RGB Fusion) to customize lighting and set PWM curves to manage fan noise and cooling performance.

Recommendations

For optimal performance, place the fan where it can provide direct airflow across radiator fins or internal components. Configure PWM curves so the fan remains in Zero RPM mode at low load if silent operation is required, and increase speed under sustained high load to maintain temperatures. Ensure the motherboard headers support +5V ARGB before connecting the lighting cable.
