Pros & Cons

Pros

✓ AirGuide anti-vortex vanes concentrate air at hot components

Cons

✗ Requires an iCUE Link System Hub, sold separately

✗ Locked to the iCUE Link ecosystem, not standard 4-pin headers
✗ 2,000 RPM ceiling means audible noise at full tilt

Manufacturer description

The CORSAIR iCUE Link LX140 RGB is a 140mm PWM case fan built for builders who want lighting and airflow on one cable. Eighteen RGB LEDs split across an inner and outer light loop give you dual-loop effects that sync with the rest of your iCUE devices, and the white shroud keeps the look consistent in a light-themed build. Behind the lighting, the LX140 RGB spins up to 2,000 RPM, moving 84.6 CFM at 4.82mmH2O of static pressure, so it has enough pressure to sit on a radiator rather than just a mesh intake panel. CORSAIR AirGuide anti-vortex vanes aim that airflow at your hottest components…

SpecPicks Verdict

SpecPicks scored CORSAIR iCUE Link LX140 RGB 140mm PWM Fan Single Pack using a rating × review-volume × price-fit model applied to published specs and reviews across the rgb & lighting category. Corsair's rgb & lighting lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for rgb & lighting of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
