If you have an Airconditioning system the fan should run as long as the compressor is running. Pressing the Econ button shuts down the compressor, then the fan will stop provided the engine temperature is below 90deg C.
The reason for the running fan is that the condenser needs cooling down to make the airconditioning work.
