Hi everyone, new poster here. I have a mid-2010 "Unibody" Macbook Pro, 2.4 GHz Intel Core 2 Duo. I opened it up some six months ago, in order to clean out the massive amounts of dust which are clogging up the fan. It didn't work. Carefully blowing compressed air into the fan didn't quite have the dramatic effect it has in videos such as this one http://www.youtube.com/watch?v=P2gtjhv7m-Q (check the 2:45 mark!). For whatever reason, the dust just kinda stayed there. So I wonder: Would it be wiser to just replace the fan with a new one?
