Manufacturer description
The Corsair iCUE Link QX140 RGB starter kit puts two 140mm magnetic dome RGB fans and the iCUE Link System Hub in one box, and it is built for builders who are tired of fighting fan cables. Each fan spins from 400 RPM up to 2,000 RPM under PWM control, moving as much as 82.5 CFM of air at 3.5mm-H2O of static pressure, so you get radiator-capable pressure when the curve ramps and near-silence when it does not. Zero RPM mode stops the blades entirely at low load. The Magnetic Dome bearing is Corsair's evolution of its ML fan technology, cutting friction at the low end of the range where sleeve…
SpecPicks Verdict
SpecPicks scored Corsair iCUE Link QX140 RGB 140mm Magnetic Dome RGB Fans using a rating × review-volume × price-fit model applied to published specs and reviews across the rgb & lighting category. Compare with similarly-priced alternatives in the rgb & lighting category before committing. 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 the QX140 fans work without the iCUE Link System Hub?
No. These fans connect through the iCUE Link ecosystem using bridge connectors and the System Hub rather than standard motherboard fan headers. The hub is included in this Double Fan Starter Kit.
How fast and how quiet do these fans get?
PWM control spans 400 RPM to 2,000 RPM, and Zero RPM mode stops the fans completely at low loads. The Magnetic Dome bearing reduces friction specifically at low fan speeds.
Are these good for a radiator or just case airflow?
They push up to 82.5 CFM with 3.5mm-H2O of static pressure, which is pressure-oriented enough for radiator and restrictive-mesh use, not just open case intake.
How many RGB LEDs does each fan have?
Each fan carries 34 RGB LEDs spread across two distinct light zones on either side, forming four light loops, and supports iCUE Link exclusive modes such as the strobing Time Warp effect.
Key Features
- Keep Cool: Powerful PWM-controlled fan speeds from 400 RPM up to 2,000 RPM, so your fans only spin as fast as you need, pushing up to 82.5 CFM of air with 3.5mm-H2O of static pressure.
- Exclusive Time Warp Lighting Mode: Equipped with 34 RGB LEDs, spread across two distinct light zones on either side, and powered by iCUE LINK for exclusive lighting modes such as the strobing Time Warp.
- Quiet Operation with Magnetic Dome Bearing: CORSAIR’s Magnetic Dome bearing retains all the performance of ML fan technology and further reduces friction at low fan speeds.
- Zero RPM Mode: Supports Zero RPM PWM signals to completely eliminate fan noise at low loads.
- iCUE LINK System Hub and Bridge Connectors Included: Chain your fans together without wires using the included bridge connectors and seamlessly connect them all to the iCUE LINK System Hub with just a single cable.
