If you ramp the clock frequency up, the voltage has to go up, unless it is already set a little higher than necessary for the default clock speed. Because as the cycle time goes down, unfortunately resistance/capacitance/inductance remain perfectly constant. The only way to offset the losses is higher voltage. And that means higher temps. And just because something runs stable for 24 hours doesn't mean it will run stable for 24 hours and 1 minute. I've seen lots of horror stories. Intel is in the process of making this impossible to do. Others will likely follow suit to avoid unnecessary warranty repair...
