Squeaking Noise: Fixed!!!

Well after being nearly driven mad by this infuriating squeaking noise for a couple of weeks, I finally fixed it. 🙂

Did I fix it by reinstalling the OS? No…

Did I fix it by upgrading the OS? No…

Did I find out it was some obscure software problem? No…

Did I send it back to Apple? Did I hell – no way I’m losing my primary workstation for 2 weeks just so they can replace a CPU fan.

Here’s how to fix it in 1 easy step (warning/disclaimer – this is not recommended, it may break your mac, invalidate your warranty or cause the sky to cave in, etc etc):

Rap the back of the Mac with your knuckles, about 3 or 4 inches above the USB ports.

That’s it! No cunning solution or workaround, just good old-fashioned physical violence. I got so annoyed by the squeak that I just gave it a whack one day as a last-ditch attempt, and the squeak stopped instantly. Came back a couple of hours later (but much quieter) – hit it again, stopped instantly. Came back once more a day later (very quiet) – hit it again, stopped instantly. It’s gone from squeaking every hour or so to not a single tiny squeak for two whole weeks (and counting).

Bliss 🙂

I guess that whack must have reseated the fan onto its spindle or something.

Now I like my Mac again…

    I’m pretty chuffed I must say! 🙂

    I guess this trick would also work with the power off, which would probably be a better idea (knocking your Mac about with the hard drive spinning – not good!). Although doing it with the power on has the advantage of knowing that you’ve stopped the squeak straight away.

    Like training a dog not to bark, if you keep yelling and saying no, eventually the dog learns.

    my cpu fan was making a squeaking sound,so since it is an old pc,i opened
    it up got so Q-tips and rubbing alcohol,took all the fans out and cleaned
    all the dirt out that those cans of compress air missed,BTW you can get a
    nice size box of Q-tips at your local dollar store for $1,07 heck it must be
    about 900 Q-tips in the box,plus the are flexible and can get into very small
    area’s,my old machine is 10 years old and still cranking,after the cleaning
    the pc sounds like a brand new machine,this kind of cleaning takes time,
    but it work fine,you should hear this old thing,just a whoosing sound,why
    waste money on those pc tech,when you can do it yourself,

    Ha! It actually works!
    Well, it’s not completely solve my problem – but it’s quieter at least
    Just have to build the confidence to hit it hard enough!

    Glad it (sorta) worked for you, Joe! Beats calling Applecare doesn’t it. 😉

    It sounded like a mouse had invaded my computer. This fix seems to work well though.

    HA! three years later and you’re STILL helping people! This squeak was driving me crazy, and after reading your post I was just frustrated enough to try it and it worked!

    Thank you for saving my sanity… 🙂

    @Mommaroth: Excellent! I’m glad the trick worked 🙂 And I’m pleased to report that my iMac is still squeak-free three years on (though to be fair the logic board was replaced 6 months ago!).

  10. Terry Says:

    How hard? I did a rap and it stopped for a few minutes. Don’t know how hard to hit it – should I get my husband to whack it?

  11. Matt Says:

    @Terry: Not too hard – maybe slightly harder than you’d knock on a door. You may have to try it a few times before it stops for good.

  12. Kerri Says:

    My iMac is doing the same thing and it’s driving me crazy. I tried the knuckles but it only worked for about 30 seconds – and actually sounds worse now that it’s started up again. 🙁

    May have to give up and take the computer into the Apple store…

  13. Matt Says:

    @Kerri: Sorry it didn’t work for you. If you don’t want to risk hitting it again then a trip to the Apple Store might well be in order…

  14. Esmurf Says:

    Seriously – AMAZING! I knocked on the back like I was knocking on a door and – voilà! Thanks so much!

  15. Matt Says:

    @Esmurf: Great to hear that this old solution is still working 🙂

  16. Tzvifl Says:

    Thank you! Thank you! I have been having the same fan squeak problem and it was driving me crazy. I have tried several software fixes without success. Your solution – bag it witb knuckle a few inches about the USB ports – seems to have worked! I can work in peace again!

    @Tzvifl: Glad it helped!
