First thing you should do is install a 180* thermostat. Then you will need a shroud to cover most of the radiator. Do you know the cfm of the fans? I looked up a BE COOL Radiator Module, it has a 19x33 radiator, dual 13" puller fans, 2000 cfm fans with a shroud. In a single fan it takes a 16" diameter, 1610 cfm puller fan, with a shroud that covers most of the radiator. Without a thermostat and a shroud it will always run hot.
