Al,

I tried a system with two large fans mounted in an metal shroud. The set up was that one fan would come on first at a low speed and increase speed as the engine temperature would increase to full speed. At a full load of the first fan, the second fan would come on full speed. The killer was that the fans would over ride the desired engine temperature and the amperage of the two fans at full speed was too high. I also had a diagonal baffle in the system to prevent pulling air in on the idle fan and not through the radiator. I made several adjustments to the fan's temperature to try to hold the engine temperature relatively constant, but it just didn't work out.
