I just picked up the $2600 model rmbp at the apple store. It occasionally makes this noise, almost like a hard drive seeking (but there is no hard drive). It seems others have had this problem as well because I found a youtube video with the exact same sound it makes. http://www.youtube.com/watch?v=rx7Nwp9SE74
It's not the fan's they are off and its not coming from the speaker. I have notice the laptop is warmer when its doing it and its usually when there is lots of wifi/disk activity going on but not related to cpu activity.
