Remember  the history! The Mag fan was Magnesium by chance. It was  
originally  
a plastic fan - (Tom Keosababian had one of those plastic babies, by   the 
way!). Midway through R&D, the plastic was being attacked by acid  fumes  
during 
test, and the decision was made at the last minute to  go to  Magnesium. 
Virtually the same molds could be  used.



Well, not quite. The planned Delrin fan had 16 vanes while the finally  
released mag fan had only 11. I don't know just how much this might have  affected 
the comparative airflows, but it sure required a different mold, I  would 
think.
