The 3 row should be fine. The main thing is get the shroud on the truck with the fan placed right inside it. The fan should have about 3/4" of the blades outside the shroud and not all the way up inside it. This is for the best air movement and it will stay nice and cool no matter what the outside tempo gets to.
