Single 120mm Magnetic-Levitation Fan

The Corsair ML120 PRO RGB is a single 120mm case fan built around a magnetic-levitation bearing. It targets builders who want low-noise cooling with addressable RGB lighting in a standard 25mm-thick frame. The fan spins from 400 to 1600 RPM and delivers 47.3 CFM at a rated 25 dBA.

PWM Control and RGB Ecosystem

A 4-pin PWM connector lets the motherboard or a fan controller vary speed across the full range without extra cables. Four center-mounted RGB LEDs provide per-LED colour control, but the lighting requires a separate Corsair RGB hub and Lighting Node PRO to function. Mounting uses the four supplied screws in standard 120mm holes.

Expansion-Only Lighting Dependency

The fan is sold as an expansion unit for the three-fan ML120 PRO RGB kit, so RGB will not work without the proprietary hub and Node PRO. Buyers who want plug-and-play motherboard RGB synchronisation or a self-contained lighting controller cannot use the lighting features of this model. The magnetic-levitation bearing still operates normally on any 4-pin header.

Questions about this item

Does the 4-pin PWM connector let me run the fan down to 400 RPM or does the motherboard set a higher floor?

The 4-pin PWM connector supports the full 400 to 1600 RPM range; actual minimum speed depends on your motherboard's PWM implementation.

Will the 25 mm thickness and 120 mm square frame fit a standard 120 mm case mount?

Yes, the fan measures 120 by 120 by 25 mm, matching the standard 120 mm mounting pattern used by most cases and radiators.

The RGB LEDs need a Corsair lighting hub and Lighting Node PRO — do I plug the fan into the hub first, then the hub into the Node?

Connect the fan's RGB lead to the lighting hub, the hub to the Lighting Node PRO, and the Node to a USB 2.0 header; the 4-pin PWM lead goes to the motherboard fan header.
