Help adding fans to my case?

So how do I add case fans? I was thinking of buying a 4 fan controller, the splicing my two side fans together so they run on one knob, the do the same with my front, as well as my top fans. That way I have 1 knob for each side of my case. But my front fans have LED lights and are 4 pin rather than 3, so how would I connect that to the fan controller and still have the lights work?
