CORSAIR iCUE Link LX140-R RGB 140mm PWM Reverse Fan - Visible RGB

In this review the CORSAIR iCUE Link LX140-R RGB 140mm PWM Reverse Fan is evaluated for builders who want striking case lighting without sacrificing cooling or noise control. The single biggest reason to buy is its reversed rotor and dual light loops, which keep the RGB ring fully visible even when the fan is mounted as intake, delivering consistent aesthetics while providing meaningful airflow. For anyone using CORSAIR's iCUE LINK ecosystem, the daisy chain capability and quiet magnetic dome bearing make this a practical upgrade for multi-fan setups.

Key Features

• Reversed Rotor: The reverse rotor design ensures the RGB ring remains fully visible when the fan is mounted for intake, preserving the intended lighting look in most case layouts.
• Dual Light Loops: Eighteen LEDs split across an inner and outer loop create richer and more customizable lighting effects that sync with other iCUE devices.
• Strong Airflow: PWM control up to 2,000 RPM delivers up to 90.6 CFM of airflow, giving the fan real cooling capacity for case ventilation or radiator mounting.
• Static Pressure: With 4.22 mm H2O static pressure, the fan has the force to push air effectively through dense radiators and restrictive grills.
• Magnetic Dome Bearing: The refined magnetic dome bearing minimizes noise and friction for quieter operation and improved longevity compared with many sleeve bearings.
• iCUE LINK Compatibility: Included LINK bridge connectors let fans be chained together into a single block for cleaner cable routing and simplified control with the LINK system hub.

Who It's For

The LX140-R is aimed at PC builders who prioritize visible RGB and clean cable management, particularly those already invested in CORSAIR's iCUE LINK system or planning multi-fan installs. Enthusiasts with tempered glass cases who want the RGB ring to show even on intake fans will appreciate the reversed rotor design.

It is less relevant for buyers who need maximum silence at near-zero fan speeds for passively cooled builds or for users who do not plan to use CORSAIR's ecosystem and prefer non-RGB, lower-cost fans. Large custom cooling shops that only care about absolute airflow per dollar might opt for other high-airflow models without lighting.

Pros & Cons

Pros

• Excellent visible RGB from the dual light loops and reversed rotor, giving consistent aesthetics when mounted as intake.
• Strong performance with up to 2,000 RPM, 90.6 CFM airflow and useful 4.22 mm H2O static pressure for radiator use.
• Quiet, long-lived operation thanks to the magnetic dome bearing and sensible PWM control including Zero RPM mode.
• Simplified cable management via iCUE LINK bridge connectors that allow daisy chaining multiple fans.

Cons

• Requires use of the iCUE LINK ecosystem or hub for full feature set and best cable savings, which may add cost.
• Single-fan purchase may be pricey for builds that need multiple fans to fill a case.

Our Verdict

The CORSAIR iCUE Link LX140-R is a strong pick for builders who want striking, consistently visible RGB and effective cooling in one package; its reversed rotor and dual light loops deliver superior aesthetics while the PWM control, solid airflow and magnetic dome bearing keep noise and temperatures in check. It represents good value for users who will use the iCUE LINK system to simplify wiring and lighting across multiple fans.

Frequently Asked Questions

Can these fans be daisy chained?
Yes, the included iCUE LINK bridge connectors let you connect fans together into a single chain for simplified cabling with the LINK hub.

Are they quiet at typical speeds?
Yes, the magnetic dome bearing and Zero RPM mode help keep noise low during normal desktop loads while still allowing higher RPM when needed.

Can they be used on radiators?
Yes, the fan's 4.22 mm H2O static pressure and up to 2,000 RPM make it suitable for mounting to radiators as well as case intake or exhaust.
