Comment 77 for bug 22336

I'm far from being an expert on thermal effects on hardware but I do have some grasp on applied mechanics. Thermal differences like the ones present in working hardware (room temperature to 60C and then 60C to 100C) induce considerable thermal stresses, so those agressive cooling cycles do indeed add quite a lot of wear and tear onto the material, which ends up trashing the stuff. So the temperature climbing over the critical limit isn't the only way to break the hardware with the hardware-produced temperature. Therefore please be careful with what you do with those thermal limits. It may cost you quite a few bucks.
