Corsair iCUE Link QX140 RGB 140mm Magnetic Dome Fan - Black

Our review of the Corsair iCUE Link QX140 RGB 140mm fan finds it best suited for PC builders who prioritize clean lighting integration and flexible cooling control. The single-fan design brings the same iCUE LINK ecosystem benefits found in multi-fan kits, letting users chain fans with bridge connectors and manage lighting and speed from a single hub. For anyone who wants bright, programmable RGB with precise PWM control and the option of Zero RPM silence, this fan delivers a compact, no-fuss solution.

Key Features

• PWM Speed Control: Fan speeds range from 400 RPM to 2,000 RPM so the fan only spins as fast as needed, balancing airflow and noise.
• High Airflow and Pressure: Delivers up to 82.5 CFM with 3.5 mm-H2O static pressure, useful for both case ventilation and pushing air through radiators or filters.
• iCUE LINK Lighting: Equipped with 34 RGB LEDs across two light zones, enabling synchronized and exclusive effects like Time Warp when paired with the iCUE LINK System Hub.
• Magnetic Dome Bearing: The magnetic dome bearing reduces friction at low speeds for quieter operation and improved longevity compared with standard sleeve bearings.
• Bridge Connectors Included: Chain multiple iCUE LINK QX140 fans without extra wiring and connect them to a single hub for a cleaner build and simpler cabling.

Who It's For

The QX140 is aimed at PC builders and modders who already use or plan to adopt the iCUE LINK ecosystem and want strong RGB effects with minimal cable clutter. It is a good fit for systems where a single, well-controlled 140mm fan is required for case intake, exhaust, or radiator use and where synchronized lighting is a priority.

Users who do not have an iCUE LINK System Hub or who prioritize the absolute lowest noise in all conditions may want to consider alternatives; the exclusive lighting modes require the hub, and noise reports from some customers are mixed under certain setups.

Pros & Cons

Pros

• Excellent lighting quality and unique modes thanks to 34 RGB LEDs and iCUE LINK support.
• Wide PWM range with Zero RPM support for flexible noise and cooling management.
• Solid airflow and static pressure numbers make it versatile for case and radiator use.
• Bridge connectors simplify cable management when using multiple fans.

Cons

• Some users report mixed noise performance; behavior can vary by system and mounting.
• Exclusive lighting modes require the iCUE LINK System Hub, sold separately.

Frequently Asked Questions

Do I need an iCUE LINK System Hub to use the lighting?
Basic fan operation works without the hub, but exclusive modes like Time Warp and full synchronized control require the iCUE LINK System Hub, sold separately.

Can this fan run silently?
It supports Zero RPM PWM signals to stop the fan at low loads, and the magnetic dome bearing lowers friction, but some users report variable noise depending on mounting and system airflow.

Are bridge connectors included?
Yes, the fan ships with bridge connectors so multiple QX140 fans can be chained and connected to a single hub for cleaner cabling.
