I use CPUCOOL. It works great.
I also heard that only AMD processors would have this issue anyways since they tend to keep on running until they burn themselves out as to if it was an intel chip, they would shut down your PC cause of some protection thingy against burning out the intel chip. Pretty cool feature, but unless it's mobile M, I'll stick to AMD
Modern AMD chips will shutdown before they destroy themselves. I know this, because my chip was overheating once when I did some work to it, and somehow the CPU fan got unplugged, and it wasn't plugged back in.
Thus, my compi kept just shutting down, and I didn't quite know why. Until I found the plug for the CPU fan dangling.
All in all, the smoking AMD video from TomsHardware may have been sweet cool and awesome. AMD I think took the publicity to heart that their processors would rather kill themselves than give any worse performance.
