Well it didn't do anything since I have a newer CPU which my version of icue can't detect, but I did rename mine instead of deleting it the an "X" appendix eg. xCorsair.Service.DisplayAdapter.exe
Don't have my older CPU anymore so I can't test it either. Regardless I won't be updating icue anytime soon, probably never as I don't see Corsair fixing this issue at all. The way they programmed icue to request/poll information about the CPU is just way too aggressive to the point that Zen has a consistent 1.4v reading whenever icue is running based on my previous experience with a 3900X.
It's now behaving as I expect it to be, inconsistent 1.0v-1.4v readings. I'm also going to block icue via firewall to stop checking for updates.
