Mine never got to that sort of heat, but you could tell it was very warm because the front wheels were never wet, the whole area got so hot water would instantly boil off.
A friend of mine recently got his whole Steam account suspended, apparently for 'suspicious activity on the Friends network'. He didn't even know they had a Friends Network.
He explained that he hadn't used Steam since Portal came out on the Mac, and asked them to compare the behaviour they were banning him for to his regular behaviour prior to that, to determine whether it was him or not. They told him to stop arguing and that he wasn't getting his account back.
Worst type of DRM in the world - someone hacks your password, you lose all your games, no argument.
