kevhill....where did you get this fan setup? looks like it would work great as well as it looks fantastic !! oh, i just saw they are dual summit 10" fans, I didn't find them on the site and is that shroud custom or part of a package?
I'm new to this site, just joined like an hour ago. It's possible that the resistor is weak, this can affect the blower performance. It's something to check out.
