Quite a few ATM's have verified Alder's experiments with their own
practical experience.  I think we can safely say that front blowing fans

Yes, I quite agree, with the note that a powerful rear mounted fan may be
able to disturb the air strongly enough throughout the mirror support box
to affect the boundary layer on the mirror face.
