If the adhesive bearing cover doesn't get blown away I would be
surprised if air induced bearing contamination would be a problem.

OTOH if you blast an airline directly at the fan from close up it will
seriously exceed it's maximum revs (slight understatement here) which
will undoubtedly cause significant damage and result in premature
failure.

Best option is to airline through the slots in the PSU case, and from
the fan side at a significant distance and/or with the fan blades
immobilised by poking a screwdriver through the grill to prevent
movement.

I agree that it's much better to airline outside, in some cases whilst
wearing a dustmask and possibly (for extreme cases) a boiler suit.
