So my 13.3" 2009 MBP unibody overheated really bad one time (somehow didn't go to sleep in my laptop bag), and ever since my 13.3" is always running hot and fan is blasting. An apple genius told me it's because the thermal paste on the cpu was ruined. How do I prevent the same thing from happening with my 15.4" rMBP? Is there an app that I can get that automatically closes programs before overheating? Is it possible to game without laptop cooling bed? Thanks.
