Hello,
I have a few Corsair devices and I started to have problems with one. I'm talking about mouse M65 RGB Elite. Since a week ago everything worked fine. I had Logo and scroll LED set to react to GPU Temperature and it worked like a charm. Next day LED switched off compleatly. Any other setting was working besides Temperature and LED was ok. From what I have learned from this forum problem was in version of iCUE. I had v3 and there is newer v4. I've installed newer one and LED is reacting to Temperature again, BUT... now it reacts to Hot Spot of GPU (Hot spots for Radeons can reach even 110*C when core temp can be at 65*C) instead of core temperature like it was before. I hope you're gonna fix this issue soon because now its usless to me 😞 this was one of the adventages that made me buy this mouse. That was a pretty neat feature because I have heavy modded PC with everything watercooled, and I like to have temperatures at hand 😄
If it helps here is my GPU model: Radeon 5700XT
