GPU "should" have limiter anyway so if the temp goes too high the computer will just switch off.

But on my previous Dell laptop (Dell default temp monitoring = pure crap) I ended up damaging my GPU because of too high temperature.
I was getting random BSOD as soon as the temp was getting a bit too high at the end, luckily I had still warranty.

Alien Swarm had this bug too, it will not cap fps by default so the GPU ends up drawing stuff at 300fps or whatever which is totally pointless and put a strain on the hardware for nothing.

Activating V-sync can fix it too since your fps will not go higher than your monitor frequency with it.
