So I maybe wrong here so bear with me. Each fan should have two connectors coming off of them. One connector should go to the MOBO, the other should go into an RGB header connector that it gives you. It sounds like you need to ensure it is connected to a Case_Fan connector and than connect to a header that is plugged into the Power supply cable. Sorry, this is off of the top of my head without coffee... but I'm sure it will fix the issue

edit: the bios might not be picking it up because the fan may not be getting enough power to recognize it.

You can also try using programs such as Asus Suite 3, or another fan controlling one and see if you can kick them on from there. If you have them plugged into the right connectors and they are still not working. Trying taking the fan out and plugging it into another MOBO if you can to see if it works there. If so, then there might be something wrong with the board.

Thank you so much for your reply FreezerBurn this info helped me out a lot.
My problem was the RGB connectors from the fan are 3 Pin and the MOBO has 4 pin RGB headers.
I have ended up purchasing a Cooler Master Hub and will be adding more fans later on.
