Look at my sig for specs. My main concern is that I will fry my CPU if I leave both processors running 90%+ ALL NIGHT and these files certainly aren't worth harming my machine. The temps are high(180-190) so I decided to put process on hold. Files are 720p and look like they'll take 6 hours or so each. My question is this, Is there a way to make handbrake only use 50% or so of my CPU's processors? Any suggestions on heat? Going to bed now without running handbrake all night, will check in the morning for updates. Thanks a lot Mac Rumors!!!
