The spudger is back out as we remove the fan.

Three standard Phillips screws and a connector are all it takes to remove the fan for dust bunny extermination.

Just in case you didn't know, dust can be a real threat to electronics by clogging air passages. Without enough air to cool heat sinks, internal temperatures can soar, severely shortening the life of electronics. Dust bunnies may also be hazardous to humans as they may contain toxins, mites, and parasites.

Unlike its cousins, the 2012 MacBook Pro does not have irregularly-spaced fan blades. Just boring old fans in here.
