Hi there, in October 2008 I bought my MacBook Pro Unibody (Details in my signature). Since about 3-4 month is gets REALLY hot really fast, also the fan is very noisy now. Now I can have my MacBook turned off for the whole day, then turn it on, watch a YouTube video and the fan is going nuts and it gets really hot. I made sure that the MacBook is on a flat surface, like a desk, but it still gets very hot. I can't even have the laptop on my lap anymore or else I would get burned through my jeans. Another problem is, that the fan is so loud, when I use my internal microphone with skype, people say they can't hear me cause of the noise! When I touch the surface of the laptop around the ESC keep, I think I could actually cook an egg! Here's a screen shot of the tempratures after booting up and watching YouTube for about 2 minutes. The temprature goes above 80 Degress as well, depending if its on my lap or the desk. And yes I made sure that the back of the laptop is not covered.
