If you go with a 3000CFM aftermarket fan it wouldn't matter if it's 4 or 5 blades because the number of blades is related to noise and not performance, right?

a 3-blade, 3000cfm fan = 5-blade, 3000cfm fan?

^^^^again what he said too....basicly if the fans you want flow more CFM than stock then they will be more efficiant. Hope we have helped.
