word to the wise, if ure running heavy programs like Logic studio, all day round, your mac might eventually die. mine did. too hot for too long will fry the components and turn the thermal paste into sand. but, take it a part, bake!! the logic board in the oven for 7 minutes at 380f. add some new thermal paste and take out all the dust. mine hasnt worked this well, and this fast, since it was brand new. it really works!
