Electric fan in lieu of Flex Fan

I currently have the same Derale fan as Keith9291 on my 440 with 3 row rad. It's marginal. I'm switching back to an engine driven, 7-blade clutch fan with shroud soon.

I think the addition of a shroud (even with the flex fan) for dragnknights would be the best first step in the right direction.

(Anyone interested in an electric fan and relay system for sale shortly? :) )
