Hey, I have a C2D MBP 2.33GHz, and I overclocked the core and memory clocks to 500/500 to play Oblivion(up from 423/450)...and my MBP barely gets warm. The only thing is that the fans seem to be running a bit more. I'm just wondering if it is okay to do this for extended periods of time as the MacBook Pro gets no warmer than it does when its not overclocked. I'm not shortening the life of the chip or anything am I? By the way, it runs like a charm
