As a follow up to some of the earlier discussion here I tested (more qualitatively than quantitatively) the bahaviour of the fans under OS X by looking at the output of smcFanControl and Tempearture Monitor (the latter displays the output of 11 temperature sensors as opposed to the 6 exposed in Linux). I was running some calculation programs that really stressed the CPU (though perhaps only one processor and very little hard disk access). First, under OS X the fans didn't start up until the processor temp sensors got into the high 70s or even 80. I think smcFanControl's temperature monitor (which did not exactly match any of the 11 displayed by Temperature Monitor so perhaps it is an average) turned red at 75 degrees. Only then did the fans ramp up over 2000 rpms. The fans very slowly moved up to 4000+ rpms (maybe even 5000) but this really required running at least one core at 100% for over 10 minutes or so and getting to a temperature of 80 degrees. Clearly this behaviour is very different than what we find under linux.
