Add a CORSAIR iCUE LINK QX120 RGB 120mm PWM Fan Expansion Kit to your system for even more lighting with four distinct light loops. PWM control lets you precisely set fan speeds up to 2,400 RPM with support for Zero RPM signals, while a Magnetic Dome bearing ensures less friction, greater longevity, and minimal noise. As part of the iCUE LINK ecosystem, all your fans can connect to the iCUE LINK System Hub (sold separately) with just a single cable, making for a cleaner build with far less cable mess. iCUE LINK opens up new possibilities for lighting and control, including the exclusive Time Warp lighting mode and smart fan curves with a built-in temperature sensor.
