CORSAIR iCUE Link LX140 RGB 140mm PWM Fan Single Pack
Bottom line: The CORSAIR iCUE Link LX140 RGB 140mm PWM Fan Single Pack: 18 RGB LEDs across dual inner and outer light loops for full-ring effects; main trade-off: requires the iCUE LINK System Hub, sold separately, so it will not run standalone.

Pros & Cons
Pros
- ✓ 18 RGB LEDs across dual inner and outer light loops for full-ring effects
- ✓ 84.6 CFM airflow with 4.82 mmH2O static pressure suits radiators and cases alike
- ✓ PWM control scales fan speed up to 2,000 RPM for load-based tuning
- ✓ Bridge connectors daisy-chain fans so a whole bank needs one cable to the hub
- ✓ AirGuide anti-vortex vanes aim airflow at hot components instead of scattering it
Cons
- ✗ Requires the iCUE LINK System Hub, sold separately, so it will not run standalone
- ✗ At 49.99 USD per single fan, a multi-fan build adds up fast
- ✗ Locked into the iCUE LINK ecosystem, not standard 4-pin PWM headers
- ✗ 2,000 RPM ceiling means audible noise if you run it near maximum
Manufacturer description
Eighteen RGB LEDs split across an inner and outer light loop give you dual-ring lighting that syncs with the rest of your iCUE RGB devices, so the fan reads as a finished piece rather than a mismatched add-on. Cooling performance is not an afterthought: PWM speeds scale up to 2,000 RPM, moving 84.6 CFM with 4.82 mmH2O of static pressure, which is enough pressure to push air through dense radiator fins as well as open case vents. CORSAIR AirGuide technology uses anti-vortex vanes to aim that airflow at your hottest components instead of letting it scatter. The Magnetic Dome bearing, a…
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.

Frequently Asked Questions
Do I need the iCUE LINK System Hub to use this fan?
Yes. The LX140 RGB connects through the iCUE LINK System Hub, which is sold separately and not included with this single-pack fan.
How much air does the LX140 RGB move?
It pushes 84.6 CFM at up to 2,000 RPM, with 4.82 mmH2O of static pressure, so it works on both open case mounts and radiators.
Can I use this fan on a radiator?
Yes. The 4.82 mmH2O static pressure rating gives it the force to push air through radiator fins, not just open case vents.
How many RGB LEDs does it have?
Eighteen LEDs per fan, split across an inner and an outer light loop, and they sync with your other iCUE RGB devices.
Is this fan quiet?
It uses a Magnetic Dome bearing, a refinement of magnetic levitation, to reduce friction and noise.
