Today we installed a high performance 2 speed Derale Fan in a 2016 Jeep Wrangler that had the OEM fan running way too much, barely keeping up (aftermarket grill and winch obstructing air flow). So, instead of getting rid of things he likes, we increased the air flow by adding a fan where there was none. :) That got the cooling system under control, and best of all, resulted in fantastic a/c temps out of the vents. (Sub 30s at exit). The fan increases speed when the a/c is active. (Those two relay's to the left of the fan supply power, one for low speed, one for high speed, each protected with a 30a fuse).
