I have a little question about my macbook. The past few days while just running iTunes and surfing the internet, my computer has been ramping up to between 135 to 160 degrees. Also it is not just the corner with the processor but almost the whole bottom of the computer is heating up. I have been making sure that the fan vent stays open, but it just keeps getting hot. Should I take it in to the Genius Bar just to make sure nothing major is wrong. are these normal temps or is something odd going on. I also have been watching the fans and they are staying at their normal 2000rpm.
