Well, as I posted earlier I have been running Seti on my PB however it will stay at around 140 F CPU temp if I leave it running for more than 15-20 min...not good. Well, I put the processor on "reduced" and now it stays at 128.8 F, had it running for 3 hours like that steady. The cooling fan is still on steady, but not at high speed. I think that a cooling pad with twin fans might get me down below 125 F CPU temp (where the fans kick on). btw, right now I have a targus Cool Pad that basically keeps it 1/2 inch off the table.
