Know before you buy
No, this is an expansion kit designed to add to an existing iCUE LINK setup. You will need the iCUE LINK System Hub, which is sold separately, to power and control these fans.
The QX140 fans use bridge connectors that allow you to snap them directly together. This eliminates the need for individual cables for each fan, letting you connect multiple units to the system hub with a single cable.
Time Warp is an exclusive lighting mode within the iCUE software that uses the fan's RGB zones to create an optical illusion. It makes the fan blades appear as if they are frozen in place or spinning in reverse while they are actually running.
Yes, these fans support Zero RPM mode. When your system is under light loads and temperatures are low, the fans will stop spinning entirely to provide complete silence.
Yes, with a maximum air pressure of 3.5mmH2O, these fans provide the high static pressure needed to push air effectively through the dense fins of a liquid cooling radiator.
While fan noise can vary based on your case airflow, the Magnetic Dome Bearing is specifically designed to reduce friction and noise. At the top speed of 2,000 RPM, they provide high performance, but you can easily manage the noise profile using the PWM control in the iCUE software.
