If you turn on the AC both the Primary and auxiliary (condenser) fan will turn on but if its off nothing. Before I replaced the fans (they both come in an assembly) the primary (driver side) fan would turn on the second i started the car and then kick off until the temperature rises to about mid way. The new fans also have a different amount of blades for some reason which I hope isn't an issue since I can't return them, thanks for any help!

That is normal operation. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Above 220F the fans will go high speed. The fact the fans come on when you have the ac running tells you the fans, circuits, relays, and ECM are good. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
