I guarantee you could make your own controller out of parts from Radio Shack and a decent thermostat.

It's not that complicated and potentiometers are always fragile, so just bypass them. People set it once and forget it forever.

Just get a no-contact thermometer and see what the stock belt fan is keeping the radiator surface at during "normal" driving, or if you have a real temperature gauge and not Ford's moron-proof "normal band" gauge, go by that. Then buy a thermostat for say 10 degrees lower for safety, and then it's just some wiring to a solenoid relay to open power to the fans. Heats up, fans go on until it's cool. Simple as can be.

I built a sprinkler valve control box out of a Radio Shack Project box, 3 9v batteries, a couple switches, a relay, and some wires and it still works fine now 3 years later(it controlled the sprinkler valve on my air cannon aka really big potato gun) Cost me like $10 of parts opposed to a nearly $100 OEM controller that did the exact same thing. Then again, I wasn't watering lawns with it either. Instead launching rolls of toilet paper several hundred feet.
