You actually don't need any software at all. Basically all GPUs in the BIOS has a failsafe function which sends a signal to auto shutdown the computer when it goes over a certain temperature. I think its usually 90-95C or so.
If you use Claymore however you can make it throttle however at a certain temperature. So if it goes over 80C or so, it can reduce the intensity and run at a lower GPU usage and get the temps under 80C.
Thanks, I was looking for something that did shut it down at around 80 C so that my house wouldn’t be a boiler room at night.
Especially in the Texas summer.
