An automobile's radiator fan will switch on and off during normal operation of the vehicle, and sometimes after the vehicle is shut off. The fan is controlled by a thermostat that regulates the temperature of the coolant in the radiator. When the coolant rises above a certain temperature, the thermostat switches the fan on to cool the radiator until the temperature drops below its limit and shuts off. The fan turning off and on is a normal part of the car's operation and is nothing to be concerned about.
The radiator fan should not run after the key is shut off. The normal cause is a failed radiator fan relay.

Fan belts are used to turn the fan in an automobile to cool off your radiator, or in a computer to pull cool air into the motor to keep it from overheating.
The fan should turn off after the engine is shut off. If it stays on, the radiator fan relay has failed.
The engine coolant fan can keep running after the engine is turned off in any car because the temperature gauge is in the radiator. As long as the radiator is still hot, the fan will keep running until the temperature gauge says it has cooled enough.
