Thermostat question
It is all in the blade and shroud design. Look at threads for the Ford Contour fan on this forum or look at this very good Mitsubishi production cooling fan; you will see much fatter blade designs, which will keep flowing at a good rate even with the pressure drop of a radiator, and a shroud that makes air flow through the whole radiator. Your fan setup pulls only through a part of the radiator and effective has reduced the radiator size to about 1/2 of it's full size when you are stopped.... assuming the fan used will push/pull worth a hoot anyway.
Since it is there, it wojn't hurt to try. But I don't expect success. The model number on your fan was requested, not just that it is 'high volume from Summit' . The best I can make of that is that it is one of those very poor electric fans, the flow of which will drop into the toilet when it is in front of or behind the flow restriction of a radiator. You have to accept that there are good electric fans and that there are crap electric fans. Even if one says it flows 5000 cfm, then it will probably drop like a rock, down 1500 cfm when pressure drop of a rad is put in front of or behind it.
