Zing! Ya got me! :-)
What I meant was that some people, with thermal sensors for their ambient
case temp. besides one for their CPU, will see CPU temps drop a bit, but the
ambient temp in the case will just skyrocket, and since Peltiers cool a
certain amount below ambient temps, at some point even the CPU temp will be
higher than before. In many cases, they have to overclock *less* than they
did because other components can't take the increased speed (memory,
peripherals, etc). Thus the need for even more case fans to rid the excess
temps.
