Fan Corsair CO-9051025-WW 12 cm Black 400-2400 RPM Magnetic Bearing

The Corsair CO-9051025-WW 120 mm black fan delivers efficient system cooling with a magnetic dome bearing and a broad 400–2400 RPM speed range. Designed for case or radiator use, this fan combines directed airflow and low noise operation to support stable temperatures in desktop systems. Dual light loops and iCUE LINK connectivity enable synchronized RGB effects and simplified daisy-chaining of compatible components.

Advantages

Magnetic dome bearing reduces friction and noise while improving longevity. Corsair AirGuide anti-vortex stator vanes concentrate airflow into a tighter cone for more effective cooling performance. Dual light loops provide enhanced RGB lighting options and iCUE LINK allows direct chaining of devices to minimize cable clutter. QuikTurn screws simplify and speed up installation without sacrificing reliability.

Suitable for

• General PC case cooling for mid- and full-tower systems
• Radiator cooling in liquid-cooling loops
• Builds that require synchronized RGB lighting via iCUE LINK
• Systems where low noise and long bearing life are important

How to use

Install the fan in your case or on a radiator using the included QuikTurn screws or standard mounting hardware. Connect the fan to the iCUE LINK chain using the single-link connector to integrate lighting and power with other compatible devices, or wire it to the appropriate fan header if used without iCUE LINK. Configure fan speed and lighting effects through Corsair iCUE software when connected to an iCUE-compatible controller.

Recommendations

Place fans to create a clear front-to-back or bottom-to-top airflow path, and balance intake and exhaust to maximize cooling efficiency; when using multiple iCUE LINK devices, follow manufacturer guidance for chain length and power limits.
