Cooling fan in the process of dying?
My MacBook Pro has begun to make noises - kind of a rhythmic rattle. It can get pretty loud. Sounds like it is coming from the left rear side of the body, which should be about where the left cooling fan is located.
I'm fairly confident the fan is going, but I'm curious if there is any way to confirm it, and/or fix it short of pulling it out and putting a new one in. Any chance it's just some dust or dirt? Or should I just go ahead and try replacing the fan?
Is this a good question?
