I tried with this tonight and dropped 5-10c temp on my GPU. I normally run at around 75c. Highest I see now is 71c, but mostly around 65c. I tried all of the heavy GPU intensive areas to try to push this back up again. New York is where I saw 71c. Queensland airport looked very ropey initially, but even that seems settled now.
I have tried a reset with everything back again, and the temp still has not gone back to previous levels. Something very weird with this one for me.
My specs are : AMD 5950, Nvidia 3090, 16GB (1900/3800). 2TB M2
If anyone tries it out let me know how you get on please. I will check mine out again in the morning. Getting late here, and maybe a fresh head will help me see this one differently.
