Fan Corsair RS140 ARGB 14 cm Black 330-1700 RPM

The Corsair RS140 ARGB is a 140 mm case and radiator fan with a black finish, designed to provide balanced airflow and static pressure for cooling PC components. It connects directly to the motherboard using a single 4-pin PWM power connector and a +5V ARGB header for lighting control, supporting popular RGB suites such as ASUS Aura Sync, MSI Mystic Light Sync, ASRock RGB and Gigabyte RGB Fusion. With an operating speed range from 330 to 1700 RPM and engineered blade and housing geometry, the fan is tuned to improve radiator coverage and heat dissipation while maintaining low noise and long service life.

Advantages

The RS140 ARGB offers direct-to-motherboard connectivity to reduce cable clutter and eliminate the need for separate fan hubs. Its blade shape, enlarged usable blade radius within the housing and Corsair AirGuide stator vanes focus airflow for better radiator fin coverage and thermal transfer. A magnetic dome bearing reduces friction and mechanical noise while extending bearing life. PWM control with Zero RPM support allows precise speed management to balance cooling performance and acoustics.

Suitable for

• Case cooling for mid-tower and full-tower gaming or performance PCs
• Radiator fans for AIO liquid coolers or custom loops
• Systems requiring ARGB lighting synchronized with motherboard software

Key specifications

• Type: Fan
• Diameter: 140 mm
• Colour: Black
• Speed range: 330–1700 RPM
• Maximum static pressure: 3.46 mmH2O (manufacturer specification)
• Connections: 4-pin PWM +5V ARGB connector for direct motherboard control

How to use

Install the RS140 ARGB in your case or on a radiator using the four mounting screws. Connect the 4-pin PWM cable to a PWM-capable fan header on your motherboard for speed control, and plug the +5V ARGB connector into a compatible 5V ARGB header to enable lighting control. Configure fan curves and ARGB effects using your motherboard’s software (ASUS Aura Sync, MSI Mystic Light, ASRock RGB or Gigabyte RGB Fusion) to match your cooling and lighting preferences.

Recommendations

Use PWM control to set appropriate fan curves and enable Zero RPM at low loads if quiet operation is a priority. When used on radiators, ensure sufficient spacing between fans and radiator fins for optimal airflow; verify motherboard header compatibility for 5V ARGB and PWM pinouts before installation.
