I've always thought this was a bit odd. My core temps are around 25*C each at idle, but at load (orthos and burnmax) they reach 54*C! This is over a double increase in temperature. My cooling design is attached. I have an AC 64 Pro with AS5. Specs are all in the left. 1.440V real voltage. Speedfan, NHC, and Gigabyte's own Easytune use to check temps.
