Corsair ML140 PRO RGB 140mm case fan 2-pack CO-9050078-WW

Two 140 mm fans for RGB builds

This pack supplies two 140 mm case fans that use magnetic levitation bearings to reduce friction and noise. They suit builders who want coordinated lighting and low acoustic output in a standard chassis. The 4-pin PWM connectors allow motherboard speed control from 400 to 1200 RPM with a tolerance of plus or minus 10 percent. Each fan delivers 55.4 CFM at a rated 20.4 dBA.

Lighting Node PRO and RGB hub included

The bundle adds a Lighting Node PRO controller and an RGB hub so both fans can be addressed through Corsair iCUE software without extra purchases. Four centre-mounted LEDs per fan provide per-LED colour control for synchronised effects across the system. Mounting strips and eight screws are also supplied for quick installation. The controller connects via internal USB and requires a free header on the motherboard.

PWM speed range and single 4-pin header per fan

Speed is limited to the 400 to 1200 RPM band, so the fans cannot spin slower for silent idle or faster for extreme static pressure. Each unit draws power and reports tach data through its own 4-pin connector, occupying two headers or a splitter. The magnetic bearing design reduces wear but does not eliminate airflow restriction from dense radiator fins or dust filters. Buyers needing variable-speed control outside this range or 3-pin voltage regulation should look elsewhere.
