I remember in one of his tuning books, David Vizard mentioned that
the blades on a plastic fan are usually aerodynamically shaped, which makes
them a little more efficient (in both air and noise volume). The problem
is that plastic ones aren't strong enough to turn the motor over with,
whereas the metal ones sometimes are (well, at least on some of my minis
they were).
