Corsair has launched its latest Hydro X series iCUE LINK XH405i RGB custom open-loop water cooling kits, replacing the older XH305i kits from 2020. The new kits feature Corsair’s latest XD5 RGB ELITE pump and reservoir, the XC7 RGB ELITE CPU waterblock, three QX120 RGB fans, and a 360mm radiator. The pump, waterblock, and fans all have the namesake iCUE LINK integration, which Corsair has been pushing throughout its entire recent generation of products.
The biggest hardware-related difference between XH405i kits and previous generation XH305i kits is undoubtedly the inclusion of iCUE LINK hardware, which Corsair recently debuted with its iCUE LINK H150i RGB AIO cooler. iCUE LINK allows individual Corsair cooling components within a system to be directly connected, primarily cutting down on cable clutter, but also offering the promise of more and finer-grained control over individual components via the iCUE LINK Hub at the center of a system. For instance, each individual iCUE LINK-compatible fan connected to the iCUE LINK hub can be set to its own speed, rather than either requiring each fan to be connected to its own fan header on the motherboard or setting a common speed for all fans via a multi-headed cable.
