My 2-day old rMBP starting making this noise, possibly from the fans. I may send it back. What do you think? I recorded a memo earlier using my iPhone. https://dl.dropbox.com/u/9775873/Memo.m4a Turn up the volume. ---------- Do you think it's something that I can and should look at myself? I mean, it can't be that hard, removing a stuck dust/paper-thing in the fans, can it?
