Fan Corsair CO-9050156-WW 14 cm Black 2 pcs 500-1700 RPM

The Corsair CO-9050156-WW is a 140 mm case fan engineered to provide balanced cooling for desktop PCs. With a speed range of 500–1700 RPM and up to 89 CFM airflow, it offers a compromise between low noise, solid static pressure and effective air movement. The fan uses Fluid Dynamic Bearing for extended lifespan and quieter operation, and supports Zero RPM mode to stop fan rotation when the system is idle. Eight individually addressable RGB LEDs deliver customizable lighting, while Corsair AirGuide anti-vortex vanes focus airflow for improved cooling whether the fan is used as intake, exhaust, or mounted on a radiator or heatsink.

Advantages

Combining up to 89 CFM airflow at peak speed with a 500–1700 RPM range lets this 140 mm fan maintain effective cooling without excessive noise. Fluid Dynamic Bearing reduces friction for longer life and quieter operation, and Zero RPM mode eliminates fan noise during idle periods. Individually addressable RGB LEDs provide precise lighting control, and Corsair AirGuide technology concentrates airflow to improve thermal performance in multiple mounting positions.

Suitable for

• PC case cooling for gaming and workstation systems
• Mounting on liquid cooling radiators and CPU heatsinks
• Systems requiring a balance of airflow and low noise

How to use

Install the fan in your PC case using the provided mounting points and screws, aligning airflow direction according to your cooling plan (intake or exhaust). Connect power and RGB control to compatible motherboard headers or a CORSAIR lighting/controller hub following the manufacturer’s wiring guide. Configure fan speed and Zero RPM behaviour in BIOS or via compatible software to match system cooling needs.

Recommendations

For optimal results, use the fans as intake at the front and exhaust at the rear or top of the case to create a consistent airflow path. When mounting to radiators, ensure push or pull orientation matches your cooling setup and monitor RPM and temperature to adjust curves for the best balance of noise and cooling.
