Unless the device automatically determines what the cpu needs to function correct (which I highly doubt) you'll need to tweak the voltage somehow also.
Think of it this way: I've got a cpu in a computer running at 4ghz at 1.5v. If I underclock the cpu to 2ghz, the vcore setting is still 1.5v so the same amount of energy is still being sent, just not being used, right?
As far as heat goes, it's the same. If you're pushing the limit at which a certain amount of voltage achieves a certain clock cycle, then there's going to be resistance. But if you're over volting your cpu, it doesn't matter if you're running 10mhz or 200mhz, the voltage is what's causing heat. Too much voltage causes heat, and too much resistance causes heat. Finding that sweet spot is the key.

that's true if the ARM processors work this way, im not sure if their voltage scales with clock speed but im sure someone out there knows
