Hi all, I have been reading this thread as I seem to have the same problem as I have a Corsair K65 keyboard, M65 Mouse and the H150i pro AIO so it was causing me a lot of problems as everything worked fine until I put iCue on.
For me I was getting 10 to 12% CPU usage in idle and after much playing around with icue, it turned out to be my Corsair Vengeance LED DDR4 3000 memory. This is the LED version red...not RGB!
After taking of the lighting profile from the RAM, the CPU usage went back to normal. If I put a lighting profile on the memory the CPU usage goes straight upto 10 to 12% again. I now am living with no lighting for the RAM and hope the next version sorts it out.
Hope this helps...
