They may have made some design improvements since I last ran a
stainless bladed fan, but the fact remains that stainless steel work
hardens rather rapidly. I had one explode on my Tiger in the late
80's. Tore a nice big slice in my "fat core" radiator (Hey! it used
to be the trick setup before they improved radiator core design). So
I'd say stainless fans have a limited service life. I prefer a large
diameter electric pusher fan on a thermal switch and eliminating the
pump mounted fan to get rid of the parasitic drag.
