Anytime I "push it" — run a lot of apps at once, or any video or iTunes music, the internal fan spools up. It sounds like a 747 at JFK waiting for takeoff clearance. (Safari is an entirely different disaster, generating a spinning beach ball whenever I have a few windows open).
Its been like that since day one, and ts beginning to drive me a bit batty . . .
Any ideas about how easy it is to swap this out? Is this an ordeal, or can I do it myself (I’ve swapped ram and hard drives in the past)
