So I got this tower and it has 4 3 pin connectors, which I'm assuming is for the fan control option. Where do these go exactly because they are no motherboard slots for them.

I just see no where to plug these pins into, or am I just completely looking over something? I know what they are from, I just have no where to plug these cables into.
