I'm about to crack into my new Mac Classic II and do all sorts of upgrades and fixes: Cap exchange, 256MB HDD, 10MB ram, and a new battery (I'm stuck in 1956). I'm thinking it might be nice to swap this insanely loud fan with something more modern and quiet. I know I can just open it and see what it is, but I just want to get everything done in one go. Anyone know what the size and specs of this fan are? None of the repair literature mentions it.
