The 13” mid 2012 requires a P4 Pentalobe screwdriver to remove case and change the fan.

The P5 is too large.

I recently replaced my battery (thanks to your awesome guidance and battery!). When I opened the cover, I saw that there was so much dust in there from over the years. I wiped off what I could and used a cotton swab to gently removed what I could. I noticed that there was tons and tons of dust on the inner ring of the fan. It seems to work but I have had issues with overheating. I am wondering whether I need to get a new fan or whether I can try cleaning the fan I have. If the latter, how do I do that? Should I just use one of those air cans that one uses for removing dust between keyboard keys? Or is there some other, better way to do it, without damaging anything?
