There are actually at least 2 types of fan clutches.  Thermostatic and
viscous.
The thermostatic type engages as the temperature of the air passing over it
increases thus making the fan turn constantly when the radiator is hot.
The viscous type only drive the fan when running at relatively low engine
speeds thus reducing the horsepower required to drive the fan.
I  don't think either would be of much help with a standard fan but may be
an advantage if a large aftermarket fan was being used.
