Oh lol. Well my PSU has been handling it fine. I'm pretty sure the wall I hit is because of the SB600. I thought about messing with the Hyper Transport but that's only the memory controller. Won't do me anything unless I'm OCing the RAM.
It's not mine but we did it at school. And no, the fan is really kind of pointless.
I havn't kept track of the temps but its been running like that for 4 months straight
