Motors controlled by thermostat do not signal the fan to run until the engine rises above normal operating temperature, and would then switch off the fan when it has cooled down again.
To ascertain if the fan is working, listen for it cutting in and out, and be checking the temperature gauge.
However if the engine shows signs of overheating, pull over and look to see if the fan is functioning. When checking for this, be sure to keep your engine running if your car is operated by the ignition switch.
