This is my first time running world of warcraft on my unibody macbook pro stock version. I noticed that the notebook gets really hot, especially on the left corner side of my macbook pro. Is it bad to have the macbook pro running real hot? Does it matter if I dont use a special fan device? I just simply want to turn on my notebook and start playing the game without worrying about the life span and heat inside my macbook pro. Any advice?
