CORSAIR RX140 PWM fans push through obstructions using high static pressure and PWM controlled speeds, built with premium Liquid Crystal Polymer and CORSAIR AirGuide technology.

WHAT IS iCUE LINK?

BUILD BETTER. BUILD SMARTER.

THE EASY WAY TO BUILD A PC
Reduce cable clutter with a network of smart, interconnected components.

LINK YOUR COMPONENTS
The iCUE LINK ecosystem uses a single connector for all iCUE LINK devices.

UNITE YOUR SETUP
Each component connects directly to the next, creating a chain of devices.

PERFORMANCE WHERE IT MATTERS

PEAK COOLING POWER
Push airflow through cases and radiators like never before at low, medium, and high speeds. RX Series fans deliver high airflow and static pressure, while keeping noise as low as possible.

AIRFLOW AND STATIC PRESSURE
A better fan relies on several key features, each improving how it handles air pressure and airflow as a radiator or case fan. RX fans were engineered to excel at both.

BLADE SHAPE
Optimized angle of attack, airfoil shape, and edge curvature ensure maximum airflow efficiency.

FAN HOUSING
The fan housing was designed to support the largest possible blade radius within its size limit.

CORSAIR AIRGUIDE
Stator vanes are angled to focus the exhaust airflow cone and improve the coverage of radiator fins and
heat dissipation.

RIGID MATERIAL MEANS CONSISTENT PERFORMANCE

GLASS FIBER REINFORCED LCP
Constructed from glass fiber-reinforced liquid crystal polymer, RX Series fan blades offer the ultimate in radiator fan blade rigidity. The premium material prevents fan blade bending or buckling under varying degrees of static pressure, ensuring that optimal radiator flow is available at any fan speed.

EVERY SOURCE OF NOISE ADDRESSED

CORSAIR MAGNETIC DOME BEARING
This improved bearing minimizes friction and mechanical noise, achieving a balance between high airflow performance and low acoustic footprint. On top of that, the reduced friction means greater longevity for your fan.

DESIGNED FOR REAL LIFE PERFORMANCE
RIGOROUSLY TESTED AND PERFECTED
Months of material and design optimization, along with meticulous testing, led to the RX Series’ unbeatable performance in delivering high static pressure and efficient airflow. These tests ensure that the fan performs exceptionally across a wide range of speeds.

REMOVING AGE-OLD ANNOYANCES

QUIKTURN SCREW REVOLUTION
Take CORSAIR's QuikTurn screws for a single spin and see how convenient fan installation can be: as robust and secure as any traditional screw, and an absolute pleasure to use. Especially when you need to use 20 or more in a build.

HARNESS THE POWER OF ICUE LINK
Unleash the full potential of your fans using CORSAIR iCUE software, from fine-tuned fan speeds to pre-set fan curves.
