I am starting to think about doing this too.
I have not gamed all day nor put any sort of 3d load on my card,but i was sitting around googling stuff,when i heard my fan ramp up,so i check and see my card right up at 96cel 😵,fan at 25%,vddc sitting at 1.158...thats higher then a game load voltage,and i had booted up the machine this morning.
Why it decided to do that is beyond me,my machine stays on quite often so luckily i was in the room to catch it doing this,i even ramped up the fan to 100% dropped it to 60cel,dropped the speed down to 25% and watched it hit 80cel in less then a few mins,no game or app running,idle gpu usage.😵
