Case and radiator cooling for custom PCs, the Corsair iCUE LINK LX140-R RGB Fan pairs strong airflow with fully visible RGB. Builders who want tidy cabling and quiet, long-lived bearings will appreciate the included iCUE LINK bridge connectors and Magnetic Dome bearing. Is the emphasis on looks and system integration worth choosing over simpler fans?
⚡ At a Glance
- • Airflow Performance: Up to 90.6 CFM, 4.22 mm H2O static pressure and PWM speeds to 2,000 RPM
- • Best for: Custom PC builders and water-cooling enthusiasts seeking visible RGB and radiator-ready airflow
- • Not ideal for: Users who want standalone lighting control without Corsair iCUE or an iCUE LINK hub
Reversed-rotor 140mm design with dual light loops and 18 LEDs per fan for strong visual impact. Magnetic Dome bearing and Zero RPM Mode aim to keep operation quiet while the included iCUE LINK bridge connectors simplify wiring.
Consistently visible RGB – with reversed-rotor and dual light loops
Reversing the rotor places the LED ring in full view while two concentric light loops house 18 LEDs per fan for inner and outer illumination. iCUE-compatible signalling allows synchronisation with other Corsair RGB components.
Uniform lighting remains visible whether mounted for intake or exhaust, making coordinated case lighting simpler to achieve.
Strong radiator cooling – with PWM control, high airflow and pressure
PWM control scales fan speeds up to 2,000 RPM, producing 90.6 CFM of airflow and 4.22 mm H2O of static pressure. That combination supplies the force needed to push air through dense radiator fins.
Controllable performance keeps liquid-cooling loops and case ventilation effective under load while allowing quieter operation at lower speeds.
Quiet, long-lived operation – thanks to Magnetic Dome bearing and Zero RPM Mode
Magnetic Dome bearing reduces friction compared with conventional bearings for lower noise and extended life, while Zero RPM Mode stops fans at low system loads to eliminate idle noise. QuikTurn screws secure mounting quickly without fuss.
Near-silent idle behaviour and durable bearing design suit living-room or stream-facing builds where low noise and longevity matter.
✨ The 4 Key Reasons for Corsair iCUE LINK LX140-R RGB Fan
- QuikTurn screws – Fast, tool-free mounting for neat case or radiator installation
- Reversed-rotor design – Keeps RGB ring fully visible in any mounting orientation
- iCUE LINK bridge – Simplifies wiring and syncs lighting across multiple fans
- Magnetic Dome bearing – Low-friction operation reduces noise and prolongs fan lifespan

❓ Frequently Asked Questions
Q: Are these fans easy to install?
A: Yes. QuikTurn screws enable quick, straightforward mounting and included iCUE LINK bridge connectors help keep cabling tidy.
Q: Can the lighting be synchronised with Corsair iCUE?
A: Yes. Dual light loops with 18 LEDs per fan can be synchronised with other iCUE RGB devices via iCUE LINK and compatible hubs.
Q: Are these fans suitable for radiators?
A: Yes. 4.22 mm H2O static pressure and PWM control up to 2,000 RPM provide the force needed for radiator mounting and effective liquid-cooling airflow.
🏆 Our Verdict
Reversed-rotor lighting and iCUE LINK integration suit custom PC builders and water-cooling enthusiasts who want visible RGB and neat wiring. Dual light loops, solid airflow and a Magnetic Dome bearing combine aesthetics, integration and quieter operation. Higher-end features and durable components favour long-term value for enthusiast systems that will be maintained and upgraded over time.
