The CPU has to be the end point as it doesn't have a RGB passthrough. Clearly something with the pump is wrong as we're both having the same issue. Hopefully we'll hear from Corsair soon.

I did some testing and found out that the pump is the issue. If I bypass the pump RGB cables and go straight to the GPU block that goes to the CPU block everything works fine. Something about the pump isn't passing on the signal to the other blocks. I'm reaching out to Corsair support.

It's a good idea but I don't have my motherboard RGB software installed. I also tried a force iCue/Commander Pro update but it didn't change anything. I'm hesitant to change too much as it was all working fine then, suddently not.

I signed up to the forums to say I'm having the same issues with my Hydro X RGB lighting. The pump half lights up (as described above). Also, I can't get the RGB on the XC7 and XG7 to react at all. This all started happening in the last 24hrs.
