iCUE Link RX140 MAX RGB 140mm Thick PWM Fan - High Flow, Low Noise

Our review of the iCUE Link RX140 MAX RGB finds it best suited for builders who need strong airflow and radiator performance without loud operation. The standout reason to consider this fan is its 30mm thick design and high static pressure, which moves more air at lower RPM than standard 25mm fans, letting systems stay cool while running quieter. It integrates into CORSAIR's iCUE LINK ecosystem for lighting and coordinated control, and the Magnetic Dome bearing promises long life for sustained use.

Key Features

• Thick fan blade: The 30mm thick frame increases the volume of air moved at a given speed, delivering better cooling than standard 25mm fans while allowing lower RPM for reduced noise.
• High static pressure: With strong static pressure, this fan pushes air through dense radiators and obstructed case paths for improved liquid-cooling and heatsink performance.
• PWM control up to 1,600 RPM: Precise PWM control lets you tune speeds for a balance of airflow and acoustics, reaching up to 1,600 RPM when needed for peak cooling.
• Eight RGB LEDs: Vivid lighting with a side window gives visible RGB effects from multiple angles, and works with linked fans for a unified appearance.
• iCUE LINK connectivity: Included bridge connectors let multiple fans be daisy-chained into the iCUE LINK System Hub with a single cable for simpler wiring and synchronized control.
• Magnetic Dome bearing: The bearing design reduces friction and noise while extending the fan's operational life under continuous use.

Who It's For

The RX140 MAX is aimed at PC enthusiasts building compact radiator loops or dense air-cooled setups who want raw airflow and static pressure without a noisy fan bank. It also matches builders who plan coordinated RGB lighting and simplified cabling via the iCUE LINK system.

Those who should look elsewhere include users who need ultra-compact 120mm sizing or who do not plan to use an iCUE LINK hub and prefer fans with integrated hubless RGB controllers; single-case casual upgraders who value absolute low cost over performance may find simpler 25mm fans more economical.

Pros & Cons

Pros

• High airflow and static pressure that keep CPUs and radiators cool even under heavy load.
• Quieter operation due to the thicker blade design allowing lower RPM for equivalent airflow.
• Clean appearance and effective cable management with the iCUE LINK daisy-chain connectors.
• Durable Magnetic Dome bearing for long-term reliability.

Cons

• Connectivity receives mixed feedback and the iCUE LINK ecosystem requires a separate System Hub for full functionality.
• Slightly larger thickness may not fit every compact case or mounting location designed for standard 25mm fans.

Our Verdict

The iCUE Link RX140 MAX RGB is a smart pick for builders who prioritize radiator performance and quiet operation; its thicker 30mm design and high static pressure deliver noticeably better airflow while allowing lower fan speeds. Paired with iCUE LINK and a system hub it produces coordinated lighting and neater wiring, making it good value for enthusiasts seeking durable, high-performance case or radiator fans.

Frequently Asked Questions

Does this fan work with standard 140mm mounts?
Yes, the RX140 MAX is a 140mm fan but note the 30mm thickness which may affect fit in some tight mounting locations.

Is a controller or hub required for RGB and linking?
RGB lighting and daisy-chaining use the iCUE LINK System Hub for full functionality; the included bridge connectors allow fans to link to that hub with a single cable.

How quiet is the fan under load?
Because the thicker blades move more air at lower RPM, users report quiet operation even under heavy cooling demands, and the Magnetic Dome bearing helps keep noise low over time.
