So I recently downloaded Borderlands 2 for Mac and I've been playing it on low settings. The entire time I play, the fans are running at 6000 rpm and the temperature sticks around 90-94 Celsius. Does this sound normal? Will it harm the computer if I play for a few hours a day this way? It seems really hot to me. I'm just wondering if I should take it to the Genius Bar or not! Oh yeah, I'm running 8 GB RAM and intel HD 4000.
