Whatever you need the fans that are controlled by the fan controller, you connect those fans into the 3pin molex (small one). And if you need add more fans that need connect to the fans controller, you want to buy the fans have the 3pin molex, if fans have the 4pin then you need buy some 4pin to 3pin adapters because the fan controller only has the 3pin molex.
So either way ima need it to be a 3 pin molex for the fan's wire?
Also, will these case fans work? ic a adapter ( i think) in their product pics or are they?http://www.newegg.com/Product/Product.aspx?Item=N82E16835146022http://www.newegg.com/Product/Product.aspx?Item=N82E16835146016
