Hm, I don't get it.

Why is the big fan? I am even now runnig all of them quiet at 1000rpm. No temp issues. Is i ran them at max then all temps drop under 40C even sub 36C. So no prob with that.

Also ran 8x390 with no extra Vchipset or LDT and no problems. So not the board or HTT...
I'm taking this baby to hell with 1.7V. If it is not stable I'm going chilled tomorrow, although 36C load with 1.65V is almost as chilled water...
