Don't be misled by the voltage rails dropping - if things are getting hot their resistance may alter or silicon gates change states. IMHO over 50 C is too hot for a cpu and shows that the cooling isn't right -either the thermal layer (paste or pad) is not applied correctly or you have a duff cooler. If you're using a pad rather then paste shame on you or whoever fitted that cooler!.

Of my 2 machines, my 2800 is running at a constant 42 degrees on load, and the 3200+ is running at a constant 19 degrees on load (http://www.aria.co.uk/ProductInfoComm.asp?ID=19756  ,airconned room 'nuf said)
