So I got my 933 last week, but I gotta tell you... It's loud. Three fans blasting are pretty annoying, but at least it shuts up completely when you put it to sleep.. What I wanted to ask was,... I hear this "squeak" which seems to be coming from the superdrive, but might be associated with the hard drive. Has anyone else noticed this noise? It happens fairly regularly, probably once every half hour or so, even when i'm not at my computer and it hasn't fallen asleep yet. I heard it three times while posting this message. If noone else has heard it, i might call it in to see what Apple can say about it.
