There is only one fan connector in my motherboard and they are for 5 pin fans. I have a J3C2F motherboard that was pulled from a Dell Optiplex. Two case fans come with my case but they are 3 pin and I don't know which adapters to buy in order to make those two case fans connect to the motherboard.

You should search for something like this:

EDIT: You can use it, that 5th pin has baisiclly no purpose, if you look at the pinout:

You said that motherboard has only one connector; the next thing you should do is to buy fan controller:
