Electric fan controller

Never been a fan of the bulb type. I have always liked the kind with an actual sending unit.....I have used a sending unit from a car that came with an electric fan in the past. Just go down to Napa and stick your head in the book looking for whatever temp you want the fan to run at, couple it with a relay (s) and yiou are good to go. If running two fans Spal has a high amperage relay available.
