    The psu on my 2008 Mac Pro started buzzing. The sound came from where the power cord plugs into the computer. I still have applecare and apple replaced the psu, but I used the machine for awhile before getting it replaced. One of the questions they asked was whether the buzzing happened when the machine was off. I don't know what that indicates.

    hmmm.....

    ive tried increasing the fan speeds and sound doesnt increase so it cant be a fan...

    its impossible to explain the noise to be honest!

    im mainly concerned for the other components i guess.......

    not sure what else i can do to test it??

    ive been running the mac maxxed out today doing encoding cpu has been at 71oC most of the day! and its still holding.......

    is it worth a genius appointment do you reckon? or should i just chill out a bit?

    They can run tests to see if it's working correctly, but I know it's a hassle to bring it in. My apple center was able to get mine back to me the same day.
