After I installed Lion on my MacBook Pro (2.53 GHz Core 2 Duo, 4 GB 1067 DDR3) I immediately started to have more heat on the MacBook. Before installing Lion; it was aprox. about 50-55C. It was usual. But now its MINIMUM 80C and going up and down between 80 to 90C. As usual; the fans started to make more voice than before and the MacBook become more warmer than before. What do you guys think about that?
