Well, when/if I get my new job in a few weeks, I am going to be doing this. Annaconda and I have almost the exact same setup other than my G0 at 3.6 and his B3 at 3.51. I was hitting 61-62C with 85-90F ambient temps as well, and would love to be in the low 50C's in the middle of summer with the heat index reaching over 100F outside. In the winter time I open my windows in my room to get it into the 50's and 60's, so this thing should be cold.
Annaconda, what memory divider are you using to get 1000mhz memory at 3.5? 8x multi?
My setting in BIOS.
Async
Manual
then change the memory to 1004 @ 5-5-5-15 2.2v for pictures go to Water cooling section.
