So yesterday my mac started making a loud humming/vibrating noise that is coming from under the keyboard, i have no clue what it is I've searched everywhere, and havent found a thing.
Now i have SMC fan control installed, and when I set the fans to run at anything above 2500 rpm the right fan won go above that, is this a fan issue?
I just got my mac mabey 5 weeks ago so its not old at all.
I do run snow leopard no clue if that has anything to do with it or what.
someone please help

    Is there a disk in the optical drive that is vibrating as it spins up?

    the fans are located on top of the keyboard. if the noise aren't comming from there, there is two other mechanical devices in your computer which is the harddisk and the optical drive.

    even if you discrimate the culprid, since your computer is still under warrenty, you should return to your service center or Apple to let them have a look and solve the faulty part or its assembly.

    Could this be the hard drive issue that I see being discussed? Do you have the 7200 RPM drive that may have this issue? If so, do you have the update that should correct it? You can search and find many other posts on that issue.

    Is the noise constant? If not how often/when does it happen?

    I'm watching these issues as my 17" is only two weeks old now. So far so good but I have my fingers crossed.

    I think I have the same issue. A constant and annoyed humming/vibrating sound which I've pinpointed to be coming from the upper right corner of my Mac where the power button is.

    I goes off when I put it in sleep mode and, of course, when I turn it off completely. It will also sometimes (temporarily) stop if I tip it on its side but then start up again when I lay it back down flat. IT'S SO IRRITATING!!! Not to mention nerve-wracking. I mean, it doesn't affect the computer's functionality or anything. Or at least it doesn't seem to. Very worrisome though. I'm gonna take it in tomorrow and see what they say... :-/

    Just got a MacBookPro 15.4 with the 500gig 7200 rpm hd. Every few minutes the mac makes a resonating humming sound that is very noticeable and very irritating. It wouldn't be so bad if the sound remained constant. It seems to be coming from the area where the hard drive is located (bottom right corner). If I gently apply pressure on the top of the case or squeeze of the case is this area, the resonating humming stops and becomes a much more pleasant constant humming (and livable).

    The laptop also arrived with a handful of small horizontal scratches in the metal case near the track pad. It appears someone at the factory was not very careful during assembly. Most are barely noticeable, but a few are noticeable.

    This is my 1st Mac - I am very very surprised by these issues - I had thought Apple had a reputation for quality products with good aesthetics (looks, performances, sounds, etc.)

    Read about other mac (Mac desktops) with similar noise issues - people solved it by placing dampening material around the hard drives to stop the adjacent metal parts from resonating due vibrations from the hard drive - not sure how this would work in the Mac laptop.

    Haven't contacted Apple - will do so very soon.
