oh btw
for ppl thinking about how to insulate these boards for such cold temps make sure you go out and buy some kneaded eraser

this stuff is just perfect

i had two LN2 bench sessions yesterday with PhII and Core i7 920 and the setups were both BONE DRY after many hours of cold............i benched intel second and lost track of time (went to bed at 3.30am) lol with about a straight 10 hour session

there is not a single bead of sweat inside or around CPU socket (plenty of ice and rest around top of pot of course heh)

i am not kidding this stuff is magic...........
