I have a decent PC, BUT my card blew a few months back and I had to throw in my old 750 ti. Because of this and the amount of time I play games I installed a 3rd party software to monitor everything. Mostly my temps.

I was worried to high hell of blowing this card as I would have to sell my left nut to replace it with a new one. But I do not hit over 7o and I run very well even with my old outdated card.

My point, I am not sure its the game. could have been just real bad coincidence/luck that you lost two pcs on same game. I think that if this was an issue it would be more known.

Are these PCs in a dusty area, or around smokers? Smoke not only slows ur fans but also coats your hardware with the same yellow gunk. causing everything on your MB to get hotter.
