Pros & Cons
Pros
- ✓ 18 LEDs per fan across dual inner and outer light loops
- ✓ 4.82mmH2O static pressure makes it radiator-viable, not just case intake
- ✓ 84.6 CFM airflow at up to 2,000 RPM PWM
- ✓ Link bridge connectors chain fans to the hub on one cable
Cons
- ✗ iCUE Link System Hub is required, so it is a closed ecosystem
- ✗ Needs the iCUE software running for lighting and fan curves
- ✗ 2,000 RPM ceiling means audible noise at full tilt
- ✗ Only two fans in the pack for a typical 3-fan radiator
Manufacturer description
The CORSAIR iCUE Link LX140 RGB dual pack puts two 140mm PWM fans and the iCUE Link System Hub in one box, so you can start a Link build without buying the controller separately. Each fan carries 18 RGB LEDs split across an inner and outer light loop, giving you two independently addressable rings per fan that sync with the rest of your iCUE devices. Cooling is handled by PWM speeds up to 2,000 RPM, 84.6 CFM of airflow, and 4.82mmH2O of static pressure, which is enough pressure to make these viable on radiators rather than case-intake duty only.

SpecPicks Verdict
SpecPicks scored CORSAIR iCUE Link LX140 RGB 140mm PWM Fan Dual 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.
Frequently Asked Questions
Does the LX140 RGB dual pack include the iCUE Link System Hub?
Yes. The dual pack ships with two 140mm LX140 RGB fans plus the iCUE Link System Hub, so it works as a starter kit rather than an expansion pack.
Can these fans be mounted on a radiator?
Yes. CORSAIR rates them at 4.82mmH2O static pressure, which the company specifically calls out as the force needed for radiator mounting, alongside 84.6 CFM of airflow.
How many RGB LEDs does each fan have?
Each fan has 18 RGB LEDs spread across an inner and an outer light loop, and the lighting synchronizes with other iCUE RGB devices in your system.
How fast do the fans spin and are they PWM controlled?
They are PWM controlled with speeds up to 2,000 RPM. CORSAIR uses a Magnetic Dome bearing, a refinement of magnetic levitation, to reduce noise and friction at speed.
Do I need a separate cable for every fan?
No. The included iCUE Link bridge connectors link fans directly to each other, so a bank of fans connects back to the System Hub with a single cable.
