Earlier today, I noticed that the fan on the right side of my MBP CD seemed to be making an odd noise. I can't quite explain it more than saying it doesn't sound "smooth" like the other fan. It becomes much more pronounced as the fans rev up, I did a hardware test to see if that would make any difference. A few min. ago though, I picked it up from my desk and noticed that there was a major crack in the wood below my MBP, the crack extends all the way through the top of my desk. Mind you, it's possible that it's the line where two pieces of wood were put together, but nevertheless, it was never like this before. I'm certain it wasn't this way until I came home for Christmas break. You can see where the crack starts on the left between my speaker jack and the USB cord for my iPod. The heat has never really bothered me before since I almost always have my MBP on a desk. The fan noise on the other-hand does concern me, any idea as to what this could be. By the way, I've sent it in twice before with the infamous "whine" and they've replaced the logic board twice, they've replaced the inverter, and I believe they replaced the video card once too. The whine is still present although much less than it was before (they installed the updated logic board) and I've taken care of it completely with ShhMBP.
