I'm putting my rig back together right now. I'm trying to see if I can improve my cable management without having to cut away some of the case. Anyhow, here's hoping (and praying) that this time round my temps will be realistic. Didn't lap the heatsink like I originally planned to, but I cleaned it really thuroughly. And I'm using AS5 this time so I'm praying it'll work right.
I'll probably only run one GTS to start with, and if temps remain low, I'll throw the second one in.
