Not a temp thing, a load thing.

Typically, the CPU only needs maximum voltage to be stable when you are pushing it hard.

As an example, my CPU needs 2.1v to be stable at 2654 MHz when fully loaded (running Folding@home, for example). However, if all I'm doing is sitting idle at the desktop, it is stable at 1.9v. So the logical question becomes, why not only run the system at high voltages when it is under heavy load? This is exactly what AMD has done with CNQ (and Intel with their equivalent). You increase the voltage to make the system able to run stably under heavy loads, and you decrease the voltage under light loads to reduce the heat output. That way, you get the best of both worlds; a system that runs cool, but still has plenty of oomf when you need it.
