How do I connect a product like this to my fans? That's where I'm stuck. I see 3 pins coming out for each fan but I have fans with 4-pin Molex connectors..

I do have A/C running in another room but not in my rig room. It would get expensive, and I don't have enough electricity, since I am using it for the video cards.
