I have a new 4 core aluminum radiator 24x16 core. In the heat of summer my temp does not stay down like it should when stopped at a light. It rises very fast but immediately drops way down when i start moving so is definitly lack of air flow when stopped. I have proven it by putting a small shop fan in front of the car when ideling and temp comes down a lot. I dont want o go through the whole debate again what i would like to know is if anyone has tried an eletric fan with 4 or 5 core radiator. The thicker cores have more static pressure drop meaning more resistance to air flow. I do know that electric fans do have a cut off point where thy cannot overcome the static pressure if it is too high. It wiill just ride the fan curve beyond a certain point.
So opinions and actual experience would be greatly appreciated. Brand names etc.
