    Hey. I just upgraded to a new MBP and both fans are running at about 2000 rpm all the time. Is this normal? And when they are at full power they are really loud. Im coming from a powerbook G4 so i dono if this is normal. Probably is but....

    Thanks,

    Jonathan

    That doesn't sound normal. What are you using your MBP for and do you have it sitting on a surface that is insulating it or not. Just had to ask, but if your just checking your email on a desk then that sounds wrong. When you say all the time do you mean immediately on start up or after a while or what.

    Actually, I think all Core 2 Duo MacBook Pros are on 2000rpm idle. It goes up to 6000rpm under full load. At least that's what I've been reading and what mine does.

    I wouldn't worry about it, eh.

    Yeah but I rarely hear my fans unless I have been working for an hour or two. This seems strange. I mean when my fans start to spin fast I hear them but normal it is very quiet.

    2000 revs is the default speed, although they should not be audible at that speed.

    My 2.0 Core Duo Macbook Pro does the same thing. Regardless of the load the fans idle at 2000-2100. If this isn't normal let me know and I'll take her in to Apple. BTW it's not a Ram thing because I'm running 2 GB's.

    I can't hear the fans unless I'm opening a 100+ photoshop file or rendering a video. Its normal.

    My C2D MBP idles at around 2000RPM as well, so this is obviously normal.

    However, when doing non-processor intensive stuff like suring the net, checking e-mail, etc I can just barely hear the fans.

    Oddly, I don't recall ever hearing them at all until after I installed Vista (which really ramped up the fans).

    Fan speed is more dependent on temperture over time than load. Run yes > /dev/nul & (twice) for about thirty minutes to see your temps soar (and fan ramp up accordingly). I think it is a nice trade off. As long as you aren't doing extensive stuff for an extended amount of time your system stays pretty quiet. Much better than how most PC Laptops are.

    2000 is the normal idle to light work rpm. It should just sound like a faint wind when you put your head close to the keyboard.

    Its no where near as loud as my roommate's acer laptop...that thing is loud idle and full load.
