I'm running a moderate OC of 4.5GHz and 1.425v for that purpose. My house will heat up during the day and so right now its kind of chilly in here and my CPU temps are around 45C. This clock and voltage should keep me well under 60C while I'm at work. Also to get 4.6GHz I need two more bumps in the voltage and thats too hot for folding 24/7.
Cool. I haven't turned my heat on yet. It's been in the 20'sF a few times and I've had the AC kick on! Stays nice and toasty in my little pad with all these rigs running! And I have a fan pulling outside air in 24/7 to boot!
