Question about fan controller

Hi, I'm looking to build a computer soon and I want to get a fan controller for the fans but I have no idea how they work. Can I control the fans that came with the case with the controller or is its control restricted to fans I add on later?

I'm going to get this case, http://www.newegg.com/Product/Product.aspx?Item=N82E16811129021, if it helps.

Thanks

That's the though, I don't know what brand fan controller has the best quality, nor do I know what to look for in a quality fan controller. How do fan controllers work? Does it plug into the motherboard and control the fans through the mobo? So all the fans need to be connected to the mobo to be accessible by the fan controller?

Thanks

spend 10$ more and go to microcenter and get a coolermaster haf 932

CM HAF 932 is by far the best... Saving up for one as we speak. (only 14 so itl take a few weeks to save up the $200 but its all good :) )

yeah. i mean 10$ mroe and u get something 2x better
