That is my point.
If the refrigerant is not hotter than the ambient air, no amount of airflow will cool it. The hotter the refrigerant, the more efficient the transfer of heat to the air through the condenser.
If you want the fan to come on earlier, get a switch that engages the fan at a lower refrigerant temperature. There really isn't a reason to engage the electric fan if the refrigerant temperature is not hot and not under high pressure, unless you just want to waste energy and wear out your fan a lot quicker.
