iCUE Link LX140 RGB 140mm PWM Fan Single Pack - Dual Light Loops

In this review the CORSAIR iCUE Link LX140 RGB fan is examined as an add-on fan for builders who already use the iCUE LINK ecosystem and want concentrated cooling with striking lighting. Its single biggest reason to buy is the combination of dual light loops with 18 LEDs per fan that deliver vivid, synchronizable effects while still providing serious airflow and static pressure for radiators and case intakes. The review focuses on real-world fit, finish, noise, and how well the fan integrates with iCUE LINK hubs and other CORSAIR RGB components.

Key Features

• Dual Light Loops: Two concentric LED loops with 18 LEDs total provide layered, customizable RGB effects that sync with iCUE devices for coordinated system lighting.
• High Airflow and Pressure: Precise PWM control up to 2,000 RPM pushes 84.6 CFM and 4.82mm H2O static pressure, giving the fan enough force for radiators and tight case vents.
• iCUE LINK Compatibility: Included bridge connectors let multiple fans daisy-chain into a single cable leading to the iCUE LINK System Hub for cleaner wiring and unified control.
• CORSAIR AirGuide Technology: Anti-vortex vanes focus airflow onto hot components for more efficient cooling where it matters most.
• Quiet Magnetic Dome Bearing: Magnetic Dome bearing reduces friction and noise while improving longevity compared with standard sleeve bearings.

Who It's For

The LX140 is best for PC builders with an existing or planned iCUE LINK setup who want high-impact RGB and effective cooling in one 140mm package. Enthusiasts mounting fans to radiators or dense front intakes will appreciate the 4.82mm H2O static pressure and 84.6 CFM airflow.

Those who should look elsewhere are users who need an all-in-one lighting solution without buying the iCUE LINK System Hub, since the hub is sold separately, or buyers on a strict budget who find premium RGB fans more expensive than basic cooling fans.

Pros & Cons

Pros

• Excellent RGB quality and layered lighting from the dual light loops for standout visuals.
• Strong cooling performance with high airflow and static pressure suitable for radiators.
• Clean wiring and easy expansion using the included iCUE LINK bridge connectors.
• Low noise and long life from the Magnetic Dome bearing.

Cons

• Requires the separate iCUE LINK System Hub to fully realize synchronized control across components, adding to overall cost.
• Priced higher than plain, non-RGB 140mm fans, which may deter strictly budget-conscious builds.

Our Verdict

The iCUE Link LX140 RGB fan is a strong pick for builders who value impressive lighting and dependable cooling in a 140mm form factor. It is good value for users already invested in the iCUE LINK ecosystem or those willing to add the hub for neat cabling and unified RGB control; otherwise its premium features may be more than a simple replacement fan requires.

Frequently Asked Questions

Does this fan work without an iCUE LINK System Hub?
It will spin and provide cooling via PWM, but full synchronized lighting control across multiple devices requires the iCUE LINK System Hub (sold separately).

Is it suitable for radiator mounting?
Yes, the 4.82 mm H2O static pressure and up to 2,000 RPM make it well suited for radiator and restrictive intake use.

Are the fans loud at full speed?
Customers report quiet operation thanks to the Magnetic Dome bearing, though noise will increase at higher RPMs like any high-performance fan.
