After a few hours of crunching the BIOS shows 52C. That's where most of my crunchers are so that's fine. My main desktop never goes above 44C, but I don't care if crunchers run a little warmer.
Wow, if I ever were to use a case again, I would want one of those. I guess cases as art justifies them in my eyes, otherwise, the extra money could go to more equipment.
