As the title says, my MBP running Mountain Lion is heating up a lot more than it ever has in the past, and I'm only running basic things. For example, right now as I'm typing this, I have open iTunes, Chrome, and the Twitter app. My computer is at 91C. I don't fully understand this, to be honest. Maybe someone can shed some light on the issue I'm having? Maybe it was just a bad install or something. Thanks for the help!
