No, the maximum fan speed is the best for AC over the long run. The biggest difference in temperature between the incoming air and the evaporator coil makes the most heat transfer. Also, the extra airflow doesn't make you feel uncomfortable. This is how central air conditioning is set up in homes.
In short term if you're going to be sitting in a car and want it cold now, then a slower fan setting will blow colder air, which feels nicer than a lot of slightly cool air.
You might be getting confused with heating fans. Too much airflow will make a lot of 80F heat, which will feel colder than slightly less 100F heat. That's why home furnaces typically run the circulation fan slower for heat and faster for AC.
