The short version
The iCUE LINK System Hub is the required controller for Corsair's iCUE LINK ecosystem, handling up to 24 daisy-chained fans, coolers and other devices through a two-channel design. It connects to the motherboard over USB Type-C, takes power directly from a 6-pin PCIe cable, and pairs with iCUE software for fan and lighting control. It only makes sense for iCUE LINK builds, and iCUE reduces brightness when more than seven devices run on one channel.

Common questions
How many devices can the iCUE LINK System Hub control?
Corsair lists support for up to 24 iCUE LINK devices across two channels, and iCUE lowers brightness when more than seven devices run on a single channel.
Does it need a PCIe power cable?
Yes. The hub takes power through a direct 6-pin PCIe connection, so a free PCIe power lead from the PSU is required.
