I know that it is a common problem for the TiBooks to become blistering hot, but is it good on the Book to get this hot? I only ask because my mom's old HP would freeze when it got too hot. I was wondering if the TiBook might get too hot. It usually gets really hot after Quake 3 (understandable) after 2 hrs or so. So should I buy a cooling pad or such to preserve the life on my TiBook?
