I'm not sure what you mean when you say the A/C isn't controlled with a thermostat. Isn't there a knob on the A/C unit itself that says "Warmer-Colder" or "Red-Blue" or something similar? This is what sets the temperature, and it is indeed a thermostat, even if it isn't calibrated in degrees. In fact, this is what makes the compressor cut off.
Th reason that the fan stays running even when the compressor is off? If you turn off the fan, room air does not circulate over the thermostat, so the thermostat doesn't know when the room needs more cooling. By running the fan, the thermostat can sense when room temperature rises, and turn the compressor back on again.
If you wanted to experiment, it is a simple rewiring job to make the fan turn on and off at the same time as the comprerssor. Simply move the fan's power wire to the same place as the compressor's power wire. I wouldn't advise doing this unless you are familiar with electricity and comfortable doing house wiring, though.
What make and model A/C do you have?
