I don't believe you have an electric fan. The fan on the vehicle is actuated by a fan clutch. It is common for them to spin the fan fast at first then slow down after a few seconds. That is most likely what you hear as far as the roaring (wind). As far as the, other noise, if you are running the defroster, the AC runs with it. Again, most times the AC will make the noise you described when it is used.
