Just think about this for a minute. The radiator fan normally kicks in
when the car is not moving. So when you are running, the thermostat is
what regulates coolant flow through the radiator(s) and tries to keep
the coolant in a certain temp range. Using a lower temp thermostat will
lower the running coolant temp.
