I also disagree whither this whole voltage not increasing BS. Anyone who understands even the most basic electronics (primarily ohms law...V=IR), will realize that voltage isn't what causes things to cook, its current. Every time the CPU does an operation the chip pulls a little bit of charge through it, and when you overclock, you increase the # times per second that this occurs. The result? More charge pumping through the Chip in the same amount of time. This current spike increases the CPU and battery operating temprature. This may not cause catostraphic failure, but will significantly reduce the life of your hardware, especially the battery.
