When I was evaluating cooling fans and shrouds, I found that how the fans are wired makes a large difference. If you plug any fans into the stock wiring, they run.... at some rpm. If you direct-wire them to the battery, with only a relay or on/off switch so they get a full 13.8VDC, ..

I am NOT getting full voltage because of undersized alternator.   when fans come on voltage drops from ~14 to 12.1 .   My directions to the shop was more and seperate runs of copper to relays and then to fans.
