Fan Corsair iCUE LINK RX140 14 cm Black 300-1700 RPM

The CORSAIR iCUE LINK RX140 is a 140 mm case and radiator fan engineered to deliver high static pressure and efficient airflow across a wide RPM range (300–1700 RPM). Constructed with glass fiber–reinforced liquid crystal polymer (LCP) blades and CORSAIR AirGuide technology, the RX140 is designed for reliable cooling performance in PC builds while maintaining a compact black appearance that fits most cases.

Advantages

RX140 fans combine rigid LCP blades and an optimized blade profile to maintain consistent airflow and prevent blade deformation under static pressure. CORSAIR AirGuide stator vanes concentrate exhaust airflow for better radiator fin coverage, while the magnetic dome bearing reduces mechanical friction and acoustic noise. iCUE LINK compatibility enables simplified cabling and direct chaining of multiple devices for coordinated control.

Suitable for

• Case airflow enhancement in mid-tower and full-tower PCs
• Radiator cooling for AIO liquid CPU coolers or custom loops
• Systems where low acoustic footprint and long fan life are important

Key specifications

• Fan diameter: 140 mm
• Speed range: 300–1700 RPM (PWM)
• Material: Glass fiber–reinforced liquid crystal polymer (LCP) blades
• Color: Black
• Connector/ecosystem: CORSAIR iCUE LINK compatible
• Weight: 0.028 kg

How to use

Install the RX140 in your case or on a radiator using the provided mounting hardware and QuikTurn screws for quick and secure attachment. Connect the fan into the iCUE LINK chain using the single iCUE LINK connector, or plug into a compatible PWM header if required. Use the motherboard or CORSAIR iCUE software to configure fan curves and monitor speeds when connected to iCUELINK-enabled hardware.

Recommendations

For optimal radiator performance, position RX140 fans to push or pull air through the radiator fins with the AirGuide vanes aligned toward the exhaust direction. Use PWM control to balance cooling and noise, and chain iCUE LINK devices to reduce cable clutter while keeping synchronized control via CORSAIR iCUE software.
