Yea that's insane. My old i7 950 xtreme oc'd to 4.2 plus single geforce 770 heats up my little office like crazy. If I leave the door shut all day while at work, it's like 20 degrees hotter than the rest of the house when I get home.

Can't remember where, but I found some site that let's you estimate the cost to keep your pc on 24/7 based on your hardware and oc. Mine is like 50 bucks a month. Cant imagine these monsters.
