Agreed, I live south of hell. Horrible, humid summers and back to bumper to bumper traffic. Thankfully no probs with AC or overheating (well, I did have to replace the blower motor last year) but still runs AC COLD no overheating in 102F temps with major humidity.

Something else is wrong with the OP's system IMHO. Sure extra fans are nice, but if those don't even help then something is def wrong.

Sombody made the point of polarity and that was entirely correct. Make sure the polarity on the fans are correct thus ensuring fan(s) are blowing in the correct direction. Push air thru the front of the rad, pull air from the back of the radiator.
