Single 140mm RGB fan for illuminated builds

The Corsair iCUE QL140 RGB is a single 140mm case fan designed for users who want vivid lighting inside a standard chassis. It ships as one unit with four mounting screws and requires a separate iCUE lighting controller for full software control.

Hydraulic bearing and 4-pin PWM

A hydraulic bearing keeps the 1250 RPM motor running quietly at 26 dBA while delivering 50.2 CFM of airflow. The 4-pin connector enables precise speed control through the motherboard, and the semi-transparent blades let light pass through without adding mechanical noise.

Replaces basic 140mm fans when RGB synchronisation

Builders upgrading from non-addressable or single-colour fans gain 34 individually addressable LEDs across four zones that sync with other iCUE devices. The jump is worth it only if you already own or plan to buy a compatible lighting controller and want per-LED animation.

Questions about this item

What does the 4-pin connector on the CO-9050099-WW control and what limits its speed?

The 4-pin PWM connector lets the motherboard or fan controller vary voltage to the motor, so the fan runs between zero and its 1250 RPM ceiling. The 10 percent tolerance means actual top speed can sit slightly above or below that figure.

Will the 140 mm by 25 mm frame with four screw holes line up with my case's 140 mm mounts?

Yes. The fan measures 140 by 140 by 25 millimetres and ships with four mounting screws that match the standard 140 mm square hole pattern used on most cases and radiators.

How do I get the 34 addressable RGB LEDs working in iCUE?

Connect the fan's lighting cable to a Corsair iCUE RGB Lighting Controller, then link that controller to a USB header. In iCUE, add the QL140 to the lighting setup and assign effects to each of the four zones.
