Recently, there has been a weird hissing coming from my Mac. It's really annoying and I have no clue if it's my fan or what. BTW, this noise goes away and comes back randomly. Thanks!
 
I, too, have heard odd sounds coming from my MBP.

I think (as other people have commented here) that for the most part, the HD is the culprit, but I've also noticed a whining sound (possibly from the power `brick`) when scrolling -- odd.
