Noisy fan no more!

Mein Problem

The right fan on my MacBook Pro would periodically go noisy-very noisy. It was embarrassing, so it had to be fixed.

Meine Reparatur

The repair was easy, but I've been in and out of my MB Pro many times. I've upgraded the hard drive twice, so replacing the fan was a breeze (pun intended).

Mein Rat

The screws are small, but reasonable to deal with. Don't forget the Torx head screws near the memory modules.

After replacing the fan, I took the old fan apart and put some high quality grease in, reassembled it and put it back in the MB Pro. The old fan is quiet (after one day at least). I suspect that the grease may migrate down the shaft after several years (this MB is over four years old). The fan design is clever because it doesn't load the thrust bearing as the magnetic field of the permanent magnet and the iron laminations of the coils keeps the fan blade suspended.

I'm keeping the new fan as a backup as you never know how long the repairs to the old fan will last.
