Pros & Cons

Pros

  • ✓ Reverse rotor keeps the RGB ring visible when the fan is mounted for intake
  • ✓ 90.6 CFM airflow at up to 2,000 RPM under PWM control
  • ✓ 4.22mm H2O static pressure suits radiator mounting
  • ✓ 18 LEDs across dual inner and outer light loops, synced in iCUE
  • ✓ Bridge connectors chain fans so a whole bank runs on one cable

Cons

Manufacturer description

The CORSAIR iCUE Link LX140-R RGB is a 140mm PWM reverse fan built for intake. Its reversed rotor keeps the RGB ring facing into your case, so front- and bottom-mounted intake fans look as clean as your exhaust fans. This CORSAIR fan has 18 LEDs across two light loops, an inner and an outer ring. You can sync them with the rest of your iCUE RGB devices. PWM control takes it up to 2,000 RPM, where it moves 90.6 CFM of air. Its 4.22mm H2O static pressure gives it enough force to push air through a radiator as well as through a case panel. CORSAIR's Magnetic Dome bearing refines the maglev…

Frequently Asked Questions

What does the reverse design on the CORSAIR LX140-R do?

The rotor is reversed, so when you mount the fan for intake, the RGB ring still faces into the case and stays fully visible.

Do I need anything else to run the LX140-R RGB fan?

Yes. It runs on the iCUE LINK System Hub, which is sold separately. The included iCUE LINK bridge connectors chain fans together so a whole bank connects to the hub with one cable.

Can the LX140-R be mounted on a radiator?

Yes. It produces 4.22mm H2O of static pressure and 90.6 CFM of airflow at up to 2,000 RPM, which gives it enough force for radiator mounting.

Is the CORSAIR LX140-R RGB fan quiet?

It uses CORSAIR's Magnetic Dome bearing, a refined maglev design that reduces noise and friction. Zero RPM mode stops the fan under light loads. An exact dBA rating isn't listed, so check the product listing for that figure.
