Before I start I have a 4gb Slim model.Well, I was waiting at the dashboard for my friend to add me. Waited about 10 minutes then decided to cut it off. I cut it off with my controller, then all of a sudden the fan inside my xbox started going crazy. It sounded like it was going as fast as it could. I had to touch the power button again for it to stop. I cut it back on and everything was fine. I just want to know if i should be concerned or not?
