Actually quite the oposite of what you are thinking is true. Allot of auto voltage settings make the voltage to high or more than needed so it will get hotter than it needs to be for your settings. You raise the voltage to get higher clocks not mess with it b/c it is to hot. No those temps are fine and remember that everyday computeing will never get you anywhere near burn in temps so you are way fine. By the way I had that proc a while back and it did 3.8 for several years at 1.4 volts. Did peak at 60c but never was an issue.
