Hi MacUsers !!!
I'm a recent switcher from Wintel to MACs (and new in this forum)

Just one month ago I've got iMac G5 17", 2Ghz., 512RAM, 160HD
Sometimes It makes incremental noise like a ‘humming’ (like a fridge, or little remote control airplane) overall when is working more than one hour, I know very well PCs fan’s sound and I think this is uncommon.
I asked to apple’s authorized technical check this problem, and after spent FIVE days with PC, they told me they didn’t hear the noise !!!!!

Is this a normal situation for this models ? (I'd think it doesn’t because noise is drilling my brain)

Is there something that I can do, check or fix by myself?

How can I record noise to send it tech guys ?

Thanks in advance !!!

    Sounds like your fans.
    What are you doing when this occurs(how many apps open, what apps, etc.)?

    Usually I’m using iTunes or HDMovie, but I’ve seen that occurs when Safari is loading a very heavy pages too.
    My concern is that this happened only after one hour of work, but nowadays is it happens just to 10 after turn it on.

    I agree - mine gets ridiculously loud too! I'm used to loud machines (owning some Wintel boxes and a G4/350 before)... of course this is all subjective... I know my Mac shouldn't be "whisper-quiet", but after paying a premium for the thing, why does it sound like it's going to explode?

    I took my iMac G5 (17" 1.8 GHz Rev A) to my local Apple Store twice and (after having the thing for 5 days) they said that the sounds coming from it are "within spec" - what in the world are they smoking?

    After I get the G5 back I'll be calling Apple Support to see if I can fare better and maybe get a (component or machine) replacement.

    hey reporteminoritario,

    I have an imac G5, first generation and the fan noise is exactly as you described. i sent it in twice and the apple store said they "could not recreate the problem" i asked if i could sit with the technical person and "recreate" the problem for him but they said they don't do this type of service.

    in all honesty, i am very disappointed with apple since i got my imac G5

    another problem was my dvd drive (that was supposed to burn dvds), it could not burn dvds. i sent it in for repair and to my horror, I found out that they installed a drive that could only burn CDs instead. I had to send it again.

    if not for the fact i need my imac for daily work, i would have banged on the doors of apple to repair the fans. i've read that some people have had some positive results after numerous replacements.

    apple is turning into a corporation that does not care about quality control or service.

    wow !!!!, mine it had same problem with DVDs drive, fortunately they fixed problem at first try,

    It seems to me that it is a common and HUGE quality control error from Apple.

    Is there way to record this kind of fan noise ?

    It is likely the CPU fan at the lower left:


    This thread contains some downloadable sounds of the iMac:


    Have fun,

    I purchased my G5 in August and have always had this noise. I tought it was normal! My son purchased one in November and his is totally silent. He feels there is something wrong with mine. The closest Apple Store is 1 1/2 hours away.

    Are there any updates to this problem?
