I've been sitting on the couch playing mario kart, taking breaks by futzing around on the facebooks and reading strategy guides. I hear my fans pop on... Sounds like a little jet plane. This always happens. But this time, they stayed on for a while. (Over 2 hours..) The room I was in started to actually heat up. I looked at iStat nano and on the overview screen, it said I was at 116˚F. (46.67˚C) I had nothing open but a single tab in safari and Colloquy. The highest my CPU got to was ~180˚F. The computer had been sitting on a coffee table-- well ventilated and all that jazz. I didn't immediately turn it off, because I thought it'd just stop on its own. Yeah.. it didn't. I moved my computer to a room-temperature granite cutting board and turned on the a/c. The MBP has finally stopped sounding like it's ready for takeoff. This happens with regularity. Because of it, I always have the computer on a flat surface for ventilation. If I use it on my lap, I get big, fantastic pink burn marks on each thigh that remain for a few hours. no pics What can I do to fix it, if anything?
