The fan is the only modular, easily-removed component in the box—which is fortunate, as it's also the only moving component, subject to wear.

Also fortunate is how easy it is to remove—four Phillips screws and a plug later and we've got it out for closer inspection.

This SUNON MagLev HA40101V4 DC brushless fan is rated for 12 volts at 0.8 W.

The fan's a standard, off-the-shelf part, so you can easily replace it if it kicks the bucket. Boouya.
