As it is, I believe my low temperature switch is something less than 
thermostat temperature, but it is positioned in the radiator at a point where the 
water has already been cooled by the time it reaches it.

I know that when I'm driving my car down the freeway and it's getting full 
airflow, both fans are normally off.   If I am forced to slow down a bit, or 
am just driving around in town at low speeds, the first fan will kick on, 
and that is sufficient to keep the car running at 180.   Only if I get stuck 
in bumper-to-bumper traffic, or sit at a red light for a period of time, 
does the second fan turn on.

I amuse myself by watching the fan light in the speedo when travelling in 
bumper to bumper traffic.   It will cycle on and off, turning off almost 
immediately when I reach speeds of greater than 25 mph or so, then coming back 
on a minute or so after I'm stopped.

I hardly ever bother looking at the water temp gauge--the car just doesn't 
get hot....
