I'm tired of the fan on my base Rev. B, and I think there is something wrong. As I've said before it will spin to 6200 with sub-60*C CPU temperatures for no reason under the lightest of tasks, and the fans will NOT come back down. UNLESS I close the lid and put it to sleep, even for thirty seconds. Then I open it back up, and it will sit at 2500 rpm happily for an hour or so and then bam--there they go again, back to 6200. While I'm there I am going to tell them the (lightly affected) lines suck too, and see if they will replace the display. Maybe I'll get lucky and get a screen better than the 9C90. If they replace the display, they just replace the display panel itself, right? Or do they just junk the entire clamshell/outer case and put an entire new assembly in?
