Well, I striked my watercooling loop last night (what a PAIN!) and re applied the thermal paste, changed the fans to pushing, refilled the coolant (no more air pockets) and it seems to have done the trick. I have a 18 hour prime stable 4.1 mhz @ 153 x 27 w/ 1.39375 and a qpi @ 1.40000 , HT on. Temps were in the 80c range at load.
