Hi disbtee,
Getting the faulty fan replaced should solve the problem.
With a single fan working, the condenser is not being cooled sufficiently and that would affect the cooling efficiency. While the car is travelling, moving air would be able to cool the condenser more and during this time the A/C cooling efficiency should be better.
Once in slow traffic, the cooling efficiency would drop.
