Single 140mm iCUE LINK fan

The Corsair CO-9051023-WW is a 140mm case fan with magnetic dome bearing and iCUE LINK connectivity. It delivers 18.1 to 95.7 CFM airflow and 0.15 to 3.79 mm-H2O static pressure at 300 to 1700 RPM. RGB illumination and a white finish suit colour-coordinated builds.

Builders who want daisy-chained RGB control

This single-pack suits users adding one fan to an existing iCUE LINK chain or starting a short run. Buyers needing multiple fans out of the box or a bundled controller should look at multi-pack kits. Systems without a compatible iCUE LINK hub or motherboard header cannot use the smart features.

Fits standard 140mm mounts with 25mm depth

The fan includes QuikTurn screws, an active connector, a passive connector and a 135mm slim-slim iCUE LINK cable for chaining. Glass fibre-reinforced frame and magnetic dome bearing reduce vibration. Zero RPM mode stops the rotor at low load, cutting noise to 10 dBA.

Questions about this item

Do I need an iCUE LINK system hub to control the RX140 RGB fan?

Yes, the fan uses iCUE LINK protocol and requires a compatible system hub for PWM speed control and RGB lighting management through Corsair iCUE software.

Can I daisy-chain this 140mm fan with older Corsair fans that use standard 4-pin PWM and 3-pin RGB headers?

No, the RX140 uses proprietary iCUE LINK connectors and the included 135mm Slim-Slim cable; it cannot connect directly to legacy 4-pin PWM or 3-pin RGB headers on a motherboard or older controller.

How do I confirm the magnetic dome bearing is running in Zero RPM mode at low temperatures?

In iCUE software the RPM reading will show 0 while the fan is idle; you will also hear no acoustic output below 10 dBA until the temperature curve triggers a start speed of 300 RPM.
