I've said it in other threads before, but I will say it here as well. Outside of academic curiosity, I would strongly discourage people from overclocking their mobile device for normal operation. These devices are nothing like regular computers they dont have the cooling systems necissary to maintain a safe operating temprature.
The folks who overclock in the lab setting are not testing their systems outside of the room temprature range, try doing that on an 85 degree day with no AC and your toast...yes that was a terrible pun.
Guys, we know the risks of overclocking. For those who didn't know the risk, I am sure they read one of the dozens of warnings from other people on this forum that have popped up almost daily.
The thing about overclocking the droid is that they actually over clocking it without messing with the voltage which is probably why there barely is any heat increase. As long you have SetCPU and have scale at 125 as the minimal that you will not see any damage.
