CORSAIR iCUE Link RX140 MAX RGB 140mm PWM Fans - Thick High-Pressure

In this review the CORSAIR iCUE Link RX140 MAX RGB 140mm PWM fans are assessed as a focused upgrade for builders who need serious cooling with refined noise control. The single biggest reason to consider these fans is their 30mm thick blade design that moves more air at lower RPM, delivering strong airflow and high static pressure for radiators while remaining relatively quiet. The included iCUE LINK System Hub and bridge connectors also simplify wiring and let users synchronize lighting and fan curves through iCUE.

Key Features

• Thicker blades: The 30mm thick fan blades push more air per revolution, so systems get improved cooling without higher RPMs.
• PWM control: iCUE LINK lets you set precise fan speeds up to 1,600 RPM for tuned performance and quieter idle operation.
• High static pressure: With 2.38 mm-H2O static pressure the RX140 MAX effectively forces air through dense radiators and restricted case layouts.
• Vivid RGB: Eight RGB LEDs and a side window offer strong lighting effects that are visible from multiple angles inside a case.
• Integrated connectivity: The included iCUE LINK bridge connectors and hub let multiple fans share a single connection and centralize control in iCUE.
• Magnetic Dome bearing: The magnetic dome bearing provides longevity and low operational noise compared with cheaper bearings.

Who It's For

The RX140 MAX is aimed at PC builders who run high-load CPUs or dense radiators and want efficient cooling with a clean look and synchronized RGB. Enthusiasts who use software fan curves will appreciate the built-in temperature sensors and PWM control through iCUE.

Users looking for simple, budget case fans with no RGB or those who cannot or will not use iCUE software may want to consider quieter or non-RGB alternatives; also expect some setup time routing the LINK connectors if your case has limited space.

Pros & Cons

Pros

• Thick 30mm blades provide strong airflow and let the fan run slower for reduced noise.
• High static pressure of 2.38 mm-H2O is effective for radiators and constrained intakes.
• Eight RGB LEDs plus a side window deliver noticeable lighting with centralized iCUE control.
• Magnetic dome bearing and good build quality give dependable longevity and quiet operation.

Cons

• Connectivity has mixed feedback; some users find the LINK system less intuitive and it can be fiddly in tight builds.
• At full RPM the fans can produce audible noise compared with lower-RPM specialty fans.

Frequently Asked Questions

Can these fans be controlled by motherboard PWM headers?
Yes, they support PWM control, but to access full lighting and LINK features you will want to use the included iCUE LINK System Hub and Corsair iCUE software.

Are these fans suitable for radiators?
Yes, the 2.38 mm-H2O static pressure rating and thicker blades make them well suited for pushing air through high-density radiators.

Will they be very loud at full speed?
They are quieter than many thin high-RPM fans since the thicker blades move more air at lower RPM, but at the 1,600 RPM maximum they are audible compared with low-RPM specialty fans.
