4 cables? there should be one passthrough molex connector (so you can connect it to a molex then still connect it to something else) then 3 fan connectors!

For the dual 200mm fans. You should have also got a kit for the front 200mm
Assuming you haven't added/changed any fans, then plug each of the 200mm fans into the fan connectors. You should have 1-2 connectors left spare after for other fans if you choose to add some.
