Hello, The back of the middle part of the lid gets hot when I am watching youtube videos. I am really surprised m fans don't go into high gear. I've noticed though if you feel the screen hinge one second the middle will hot then the next it will get cooler than keep on going back and forth until I log off youtube. Then if I put it to sleep or shut down right after the back of the middle put of the lid is hot. I checked the CPU while on youtube and it was at about 30% or so. If I watch videos on another site like mtv.com right after I am youtube the fan kicks into high gear. I also have my fans up to about 50% now with fancontrol as when I didn't and was on youtube I would get a quick line vertically through the internet window and when I went to close the window, I would get like a flash. I was worried that youtube may be overheating my macbook but since I turned the fan up that hasn't happened. Is this happening to anyone else?
