I am a bit concerned with the temps of my stock CPU in my Mac Pro 5,1 3.2 machine. When running handbrake overnight I am seeing temps remain around 185F to 186F in iStat. It idles around 89F in my air conditioned basement which stays around 66F. Are these temps something to worry about, and as a side, will it be worthwhile to upgrade at this point? My reasoning is that if I need to reapply the factory thermal paste, I might as well upgrade the CPU while I am at it... I do use this Mac for some home movie editing, converting our movie collection to digital, and other than some gaming in bootcamp, I am getting by with four cores for work which is the most important.
