Single 120mm PWM RGB fan for iCUE LINK ecosystems

This single 120mm PWM fan uses a Magnetic Dome bearing and Corsair AirGuide technology to deliver 10.5 to 74.2 CFM airflow and 0.12 to 4.38 mm-H2O static pressure. It operates between 0 and 2100 RPM with a noise range of 10 to 36 dBA and includes a Zero RPM mode for silent idle. The black frame houses vivid RGB lighting controlled through the iCUE LINK system.

Builders adding one fan to an existing iCUE LINK

This unit suits builders expanding a current iCUE LINK loop because it includes both Active and Passive connectors plus a 135mm Slim-Slim cable for daisy-chaining. It is not suited for users who lack an iCUE LINK controller or hub, as the fan requires that ecosystem for PWM control and RGB management. Buyers wanting a standalone fan with a bundled controller should look at a different product.

Zero RPM mode and 2100 RPM ceiling define

The fan stops completely at 0 RPM and spins up to 2100 RPM +/- 10%, giving a broad curve for quiet idle and high static pressure when needed. Magnetic Dome bearing construction and glass fibre-reinforced frame support that range without mechanical contact wear. QuikTurn mounting screws and two decorative plates are included for quick installation in any 120mm case mount.

Questions about this item

Do I need a Corsair iCUE LINK controller to run this fan?

Yes, the fan has no built-in controller and requires an iCUE LINK system controller connected via the supplied active connector and 135mm slim cable for PWM speed and RGB control.

Can I daisy-chain this RX120 with my older 4-pin PWM fans on the same motherboard header?

No, the RX120 uses iCUE LINK proprietary connectors and must be linked in series with other iCUE LINK devices; it cannot share a standard 4-pin header with legacy fans.

How do I confirm the fan is operating in Zero RPM mode at idle?

In iCUE software the RPM reading will show 0 while the temperature source is below the configured threshold; the magnetic dome bearing allows a true 0 RPM stop without stalling.
