I also put two electric radiator fan in the mid center intake hole of my Mid Cruise air. Just a dash switch to a relay and on they go. I have yet to have the chance to see if they do any good. My mid A/C is my problem child, major dismantling to get to and intake and exhaust close together under the bus. I these fans help but not enough I will add misters. I believe Jim Shoen found out that the mister will not hurt the AC fan or coils.
