So I'm looking at a dual fan system for a 2014 Taurus https://www.rockauto.com/en/catalog/...+assembly,2181
and am wondering why these fans can't be run/triggered with a simple thermo switch. I mean leading into the motor are three wires, just like a normal, older Taurus fan motor. Enlighten me.
If it's 2 wire it probably can. The newer fans are usually controlled with pulse width modulation (PWM). The control the speed of the fan with burst of voltage. I would still research the specific car schematics to verify I am not waisting my time using it.

Many aftermarket controllers are now using PWM. They are installed with fans that did not come with that type of controller. How would the newer fans differ from the older ones?
Thanks.
My only concern would be if they changed the voltage the fan is capable of handling on a newer car. The likelihood of it being different from the car is low but with hybrids capable of higher voltages I would investigate to make sure they were 12v.
When PWM control is running the fan at high it is provided max voltage continuously or close to it.
So chances are the new fans are not much different than the old.
If you haven't already I'd get a basic IR temperature gun and take readings at the inlet and outlet of the radiator so you know exactly what you're up against. What is the basic system capable of in terms of temp drop when the outside temp is X? Then when you introduce the electric fan or fans what does it add to temp drop when the fan/fans are at X rpm's. Get a clear idea what the most effective rpm for your fan/fan's really is. No sense in spinning them faster than you'll ever need. With that information design an rpm control that will control fan speed based on the variables of outside temperature and motor temperature.
