Cautionary advice:

High speed air can create static charges that destroy static sensitive
components (e.g. what you're computer is full of).  Careful blowing out
of heatsink fins wouldn't be a problem, but blowing across components
can be, and that's hard to avoid unless you can actually remove the
heatsink.

Blowing into a fan can blast muck into the bearings, stuffing things up
in a new way.

Blowing into a fan blade so it audibly goes WHEEEEEE as it spins around
can (depending on the design of the fan's electrics) cause the fan to
act like a dynamo, and inject current into some circuit that never
expected to receive it.

High pressure air could blow off any components with a weakness.
Perhaps something that, otherwise, wouldn't have broken.
