    Hey man. Download smcFanControl. It it will let you set your fan speeds. If your fans don't work I'm surprised your MBP has survived 2 months. I'm pretty sure they do its just you haven't gotten your temps high enough for them to kick in. Mine don't rise until I hit 165F so.

    anyway you can download it here

    yes there is somthing you can do
    open terminal
    type yes >/dev/null &
    press return
    type it again
    press return
    now go check activity monitor and make sure the CPU is maxed out on both cores
    the fans should kick in after a short while
    if they dont kick in after 8-10 minutes than your fans dont work

    simpler test

    apple.com/trailers/

    run enough high def traliers that they start to skip, mute the sound. after about 30 seconds you'll hear the fans... or smell burning.

    have you ever had a mac before? if not, i understand. it takes a while to get used to the higher degree of engineering.

    That just made me really think about the whole MBP vs MB debate I have been thinking about. I'm getting the MBP for that higher degree of engineering! :cool:

    That's because the MacBook's fan is more of a external unit that hovers over the processor - exactly like this:

    The fans in the MacBookPro are encased as part of the heat pipe that's under the logicboard.. therefore sound and vibrations would have to travel further - trust me, it's for the best! ;)

    And if anyone likes to see more.. go here

    I assure you, your fans are running. When I first got my MacBook Pro, I thought by default the fans didn't run unless they were needed. I was surprised when I download the iStat Pro widget and found that they ran at a constant 2000rpm minumum.

    They're extremely quiet. Don't fret; just thank :apple: for a quiet computer. :)

    i realize this was an old thread, but at least i used the search tool...


    Anyway, i too thought that my fans did not kick in so i tried the open as many HD trailers as possible and wait. Except i did it with a twist, opening every app in my dock at the same time (majority of Adobe CS3, and a few other less intensive apps). It turns out that the new Penryns kick in at around 80C

    80C? I feel like it should be shutting down at that temp =x

    i don tknow about you guys but i've had a first gen mbp from my friend and neither fans were turned on for the first month i was using it. i had istatpro and smcfancontrol and both showed 000rpm. i tried listening to them and heard nothing. it was running ridiculous hot where it will burn my legs if i had a movie running. i finally opened it up when my 320gb hdd came in. i had the top opened and turned on the mbp and neither one of them was running at all. i ripped open the whole laptop and checked on the whole thermal grease issue and which it did so i cleaned it all up and reapplied new grease. when i put it back together somehow my right fan started working and i can definitely hear it. my left one is still not running at the moment. so to all you guys saying the laptop wont work without fans running, that might not be true since mine went at least a month without them running. who knows how long they werent working since i got it from my friend.
