i've installed my Mach II (thanks tc_overclocker) but had to remount it 5 times to get a good contact. now @ 1.75v my cpu idles at -35 and load -5 (compressor at -30) is the heating element effecting the temps? with my Mach I my load was around -20.
i decided to remount the thermal bus, but this time i secured the brass bracket thing so it did not move around and now its perfect - priming @ 1.75v -24C
