The Corsair iCUE LINK QX140 RGB White is a two-fan kit built around Corsair's newer iCUE LINK daisy-chain ecosystem, which replaces the usual tangle of separate PWM and ARGB headers with a single connector per fan that can be linked directly to the next fan in the chain. Each 140x140x25mm fan uses a magnetic dome bearing and a 7-blade PWM impeller, running from 400 to 2,000 RPM with an onboard temperature sensor, delivering 12.1 to 82.5 CFM of airflow and 0.19 to 3.5 mm/H2O of static pressure depending on the curve set in iCUE, so the same fan can be tuned as a quiet, low-static-pressure case fan or a higher-pressure radiator fan. Each fan carries 34 addressable RGB LEDs arranged across two double-sided light loops, giving a fuller lighting effect than a single ring of LEDs on the fan frame. Rubber corner pads reduce vibration transfer into the chassis. The kit bundles an iCUE LINK System Hub, the small controller box that can manage up to 14 iCUE LINK devices from one motherboard header, cutting the internal cabling of an RGB-heavy build down to a single run back to the hub. It suits builders standardizing on Corsair's iCUE LINK platform for a case with 140mm fan mounts, whether for front intake, radiator support, or general case airflow with coordinated RGB lighting.
