CPU _should_ have survived the thermal management on them is pretty good these days.
I actually wonder if the motherboard is the where the problem is even tho its not intuitive as that being where the fault is as those 470s will take a ridiculous amount of heat and survive ( I have some experience at trying to kill em )
