Outer fan cools condenser coil as well as compressor. Even though the cycle is turned OFF the compressor needs to be cooled continuously.

What would cause the outside air conditioner fan to stay on constantly when the inside unit is turned off?
There are two reasons for the outdoor fan to remain on while the system in side is off . The first is that the contactor on the outside condensing unit is frozen closed. In this case the 240 volts supply to fan and compressor will not be turned of when the inside system goes off. If both outside fan and compressor remain running for a time then the system will freeze up and ice will form. The second is that 24 volts is still be supplied to the outside contactor even though the thermostat is satisfied. The 24 volts would be supplied by an electrical short between the red and the yellow wires . The short could happen any where along the thermostat wiring where the two bares have become bare and are touching.
