    So far I'm finding little, if any, correlation between the heat and the noise. Each time the noise started... there was no significant change in temperature. The most recent time the noise came on, the temp. was only 56C (not really that hot)--which has been typical, at least my experiences.

    Same here then. A friend of mine suggested heat build up from the HD where it's seated and that it simply starts to vibrate as the metall enclosure expands. It would have nothing (or little) to do with processor heat and thus wouldn't show up at any particular temp when running CoreDuo Temp for instance. That also makes sense when taking into fact that the sound stops when I tilt the machine and/or gently shake/rock it.

    I think...

    There's no immediate rush on my wife's part to take it to the repair shop so we'll leave it be and see if it it turns out that more computers are affected and they decide to do a recall, as with the Macbook Pro battery and logic board deal.

    Cheers

    ok it is probly your fan motor to test that

    boot from your install cd go to the utilities menu and open the terminal then run the command yes > /dev/null


    then go to file/new shell and run it again this will boost your cpu to 100% cuaseing the fan to kick in and if you here the problem with the cd in then its a hardware issue if not then its software

    Sorry, didn't work for me at least. Well, the fans did kick in but the sound wasn't there. I'm still suspecting vibrations from the HD. I wish there was some way I could put the HD to sleep manually to see if I'm right.

    On my computer there is an option to turn off the Hard Disk only "when possible". (It's in System Preferences > Energy Saver > Sleep)

    Maybe if you can activate that you'll be able to judge if the Hard Disk is the source of the noise.

    (Note: I have a different computer and version of Mac OSX to yours, so I don't know if yours will have the same function)

    Yep, did that (booted from CD). I think I have to do it again after the sound has manifested since it needs to be warmer first. I'll keep you posted.

    And the put to sleep when possible is on my system too, but I was hoping there'd be a way to do it manually =).

    Cheers

    I booted from the install CD and there was no noise--I basically had the same results that my new pal, Peter, did.

    Erik, I can't for the life of me understand what this sentence means... could you please retype it or elaborate on it further:

    ps if the sound wasent there from booting from teh
    install cd the reinstall your system software see of
    ot helps


    Thanks all for your help so far... I'm really trying to solve this for myself because being in New Orleans, the nearest Apple Store is in Houston (a 700 mile round trip)... and I'm trying to avoid having to take a day off to drive there. So again...thanks for all your help so far. I really appreciate it.

    haha sorry i was in a hurry when i typed that



    I meant to say

    If there was no noise from your fan when you were booted from the install CD
    then the noise you are hearing when you are booted from your regular system folder is a software related issue. I suggest reinstalling Mac OS X to see if thise helps your problem.

    If it does not call apple Technical Support.

    There number is 1-800-275-2273

    Tell them you are hearing odd noises from your fan and you want the fan replaced. They will send a box to your house and all you need to do is pack up your computer and then drop it off at a FED EX or DHL.

    Eric,

    Thank you for all your help so far. I have a question for you regarding reinstalling OS X: Do I have to erase everything and reinstall a fresh copy or can I do this while keeping my user data/preferences/applications/etc.?
  • 29. Re: MacBook Making Loud Noise
    EricLErak Level 2 Level 2 (380 points)
    Yes you can do that its called an archive and install
    this will transfer all your user data ,music, documents etc


    When you Archive and Install it will install a new system folder in your HD, But it will still keep your old one it will be named something like Previous System.

    When everything is loaded and your at your desktop i recommend deleting or securely deleting the previous system folder to save you a few gigabytes.
