NikleinR6 comments on the extra fan setup:
-Attached (2) 6" fans to the backside of the new large heat exchanger up front that are controlled by a switch hidden in the ashtray. I do notice a difference. It would take longer for the IAT's to drop once i got off the highway after a long pull, so i installed the fans. They help tremendously while i am sitting at redlights and moving slowly. They don't reduce the temps more than if i didn't have them, but they absolutely do reduce the recovery time it takes for the temps to drop back down after they rise
