I've had my Apple MacBook for a couple weeks now, but I'm getting worried. Coming from the gaming world, I know how important it is to keep things cool ( PC has 4 120mm fans, sounds like an Airplane!) But my notebook gets very hot. I mean so hot where I can't even set it on my lap. Will this shorten the life of my new baby? After spending $2300, this sucker better last a long long tiime.
