There are , depending on the mother board, a couple of places to plug in fans on the mother board. If not you can always get a double connector and exstention to connect to the nearest power plug. Or you can get a fan controller and have the fans set to a certian temp.
Yes, I have the Y cables... Since two of the fans connect to CPU fan on MB would the Corsair fan controller on the cooler recognize the 2 additional fans and lower and raise the fans in unison? So would all 4 fans connect to the CPU fan connection?
