JB, I went with a SPAL fan which is 2 speed, rated by amp draw and I opted for the SPAL Programmable Controller that operates the fan automatically, low speed above 195F, high speed above 210F and back to low speed below 200F. Turning on the AC (very rarely used) triggers high fan speed. At normal cruise the fan's not running, even on a hot, humid day.
