ok so i want to add 1 or 2 case fans on my dimenson 2400. My question is where do i connect the fans in if i only have one 3 pin connector on my mobo. my other question is do the fans that say 3/4 fit on my mobo connection. i was thinking of some of these http://www.newegg.com/Product/Product.asp?Item=N82E16811999465
