I have an 1800+ with an el cheapo HSF, generic, and I'm hitting 50º. I was hitting 59, so then I took the plug from the cpu fan out of the motherboard, and spliced it into the power supply. I test it again after some 3dMark, and its at 69!!!!!!!!!!!... So i opened it up, and I noticed I spliced into the 5v, so then i spliced into the 12v, and I'm down to 50.. is that high?
