140mm Magnetic Levitation RGB Fan

This 140mm case fan uses a magnetic levitation bearing to reduce friction, delivering 55.4 CFM airflow at a maximum noise level of 20.4 dBA. It targets builders who want quiet, addressable RGB cooling for a standard 140mm mounting point. The PWM control allows speed adjustment between 400 and 1,200 RPM to balance airflow and acoustics.

RGB Requires Separate Lighting Node PRO

The dynamic RGB lighting relies on four independent center-mounted LEDs, but the fan itself includes no controller. Full RGB functionality requires a separate Corsair RGB Lighting Hub and Lighting Node PRO, making this single pack an expansion part rather than a standalone lighting solution. A standard 4-pin PWM header controls fan speed only.

Single Fan Expansion Pack Only

This product ships as a single fan with four mounting screws and no Lighting Node PRO or hub included. Buyers who want an out-of-the-box RGB ecosystem or a multi-fan kit with the necessary controller should look elsewhere. The magnetic levitation bearing and 25mm thickness suit standard case mounts needing low-noise intake or exhaust.

Questions about this item

Should I buy this single 140mm fan or look for a multi-fan kit?

This is a single 140mm expansion fan intended to add to an existing ML140 PRO RGB kit with Lighting Node PRO.

What does the 55.4 CFM airflow figure mean for my case cooling?

At full 1200 RPM the fan moves 55.4 CFM while producing 20.4 dBA, so it delivers strong airflow with low noise inside a typical case.

Does the 4-pin PWM connector control both speed and RGB lighting?

The 4-pin PWM connector controls fan speed from 400 to 1200 RPM; RGB lighting requires a separate Corsair RGB Lighting Hub and Lighting Node PRO.
