Corsair LL140 RGB 140mm Dual Light Loop PWM Fan, Single

Corsair LL140 RGB 140mm Dual Light Loop PWM Fan, Single

A single Corsair LL140 RGB expansion fan for adding to an existing LL-series kit with a Lighting Node PRO.

The LL140 RGB carries sixteen individually addressable LEDs arranged in two separate loops, one around the outer frame and one around the hub. Because each loop is driven independently, iCUE can run effects that flow between the two rings rather than simply cycling colours. This single pack is sold as an expansion: it has no controller in the box and its lighting will not work without a Corsair RGB Lighting Hub and Lighting Node PRO, both of which come with the LL140 twin-pack kit or the Commander PRO. If you already own one of those, this is the fan to add for a third or fourth position.

Cooling performance

The 140mm blade is shaped for low noise and runs from 600 to 1300 RPM under 4-pin PWM control, delivering 51.5 CFM and 1.52 mmH2O at full speed at a rated 25 dBA. It suits front intake and top exhaust positions and 140mm radiator mounts where quiet running is the priority.

Fitting and control

Fan speed comes from the motherboard through the PWM connector; lighting plugs into the RGB Lighting Hub and is controlled in iCUE alongside your other Corsair devices. Four mounting screws are included and Corsair provides a two-year warranty. Punch can add this fan to a new build with the matching hub and node.

Ideal for

• Expanding an existing LL-series kit or Commander PRO setup
• Replacing a failed LL140 in a current build
• Quiet 140mm intake or exhaust positions with dual-loop lighting
