You may want to fiddle with thermistor/diode settings, also check the BIOS temps please how they are diffrent? > One other thing, VCore1 is a bit fluffy, with occasional spikes to 1.8V > and dips below 1.4V (should be 1.5V). Does that sound reasonable? Hmm this should be stable maybe it is not a thermal problem at all? Tried with another PSU? Regards Rudolf
