Video I just purchased this RMBP about three months ago and today I start it up and I start hearing this sound coming from the RMBP. I'm taking it in to an authorized mechanic later today (we don't have an apple store around here) but does anyone have any ideas what it might be? Broken fan? I do have one other question. I had my computer on vacation with me two months ago and it got a small chip on the corner. I have no idea how it happened and it definitely wasn't dropped or anything. Will that invalidate my warranty? If I find out this computer I spent a good chunk of change on can't be repaired today is going to be a pretty awful day.
