One of the cheapest ways I've seen to control a thermofan is to use one of these:

You can use the ECU thermosensor voltage to switch the fan at any temp. I don't like thermoswitches that don't directly sense coolant temp (just radiator surface temp) but I also don't like the ones with sensors you have to poke under the radiator hose. This way solves both problems.

I used the cheap non-adjustable probe switch from a parts store.
I positioned the probe through the radiator fins just below the hose inlet.
I used a relay to carry the load, and a diode from the AC clutch to turn on the fan when the AC was running. Power was directly from the battery, through a circuit breaker.
Under $40, simple, rock solid reliable.
The only trick is the switch-off cool down can mess with some alarm systems.

I seen it first hand with hIGGI's ****.
I've had bad experiences with those generic probe-in-rad-core thermostat controllers too - I had one until it died and prevented the fan from turning on.

I had terrible experiences with the flex-a-lite thermostat switch. It would not work properly from the day I got it. I finally bought a generic one and it worked beautifully and I've never had a single issue with it.

I've had a Flex-A-Lite thermo switch fail also, after about 3 months use.
The cheap simple parts store thermo switch was working for 2 years when I sold the car.

I've seen those switches fail like crazy. My friend had a 240SX with one and it was dead when he got the thing.
I just let the MegaSquirt control my fans

I still can't remember. It was a generic one from some online parts store. I thought it was summit racing, but I did a search on there and the one I have doesn't seem to be present anymore.
