White 140mm RGB case fan

The Corsair CO-9050138-WW is a single 140mm PWM fan finished in white with eight addressable RGB LEDs. It suits builders expanding an existing iCUE SP RGB ELITE cooling loop or adding coordinated lighting to a new build. The hydro bearing and AirGuide vanes are designed for quiet operation across intake, exhaust or radiator positions. Buyers who need a bundled controller or a multi-fan kit should look elsewhere.

PWM speed range and airflow

The fan spins between 450 and 1200 RPM with a tolerance of ten percent, delivering 23.07 to 68.11 CFM at a noise level of 18 to 26.8 dBA. This wide range lets the motherboard or iCUE software balance silence and cooling without a fixed high-speed setting. If your chassis requires a specific static-pressure rating or a narrower acoustic ceiling, this model may not match those targets.

Standard 4-pin mounting

Installation uses the four included screws and a regular 4-pin PWM header; no proprietary connector is required. RGB control needs a separate Corsair iCUE lighting controller, so the lights will stay at default patterns until that hardware is added. A common issue is forgetting the extra controller, leaving the LEDs unsynchronised with the rest of the system.

Questions about this item

What does the 68.11 CFM maximum airflow deliver when the fan is installed in a case?

At full speed the fan moves up to 68.11 CFM, and the AirGuide anti-vortex vanes concentrate that flow so it reaches components directly whether the fan is used as intake, exhaust or on a radiator.

What does the 4-pin PWM connector control in practice?

The 4-pin connector lets the motherboard or a fan controller vary speed precisely between 450 and 1200 RPM, so noise stays near 18 dBA at idle and rises only when cooling demand increases.

Will the 140 mm by 25 mm frame fit my case's mounting points?

The fan measures 140 mm square and 25 mm thick (5.51 inches by 0.98 inches), matching standard 140 mm mounting holes; four screws are included for installation.
