Hey, Loving the new(ish) MacBook One thing though: For the first time, I used the MacBook in a quiet environment, and I noticed that a small grinding noise is coming from the fan. Kind of like it's rubbing against something. It's not causing any performance issues, it's just kind of annoying. Do you know what the problem might be and if it can be fixed under warrenty? I'm super careful with all my electronic gadgets. If I put my ear right up to the air vent under the "MacBook" logo, it sounds like there might be a speck of plastic caught in the fan or something... Thanks in advance.
