Case fan enough?

I was planning on getting the 680s 4gb edition and sli them to run a surround setup on my first build and I was wondering if I would need any more fans or if this is plenty enough in this case

It looks like enough. 5 120mm plus top fan. This case came out before motheboard started having fan plugs on board. All these fans are 2 wire so even if MB plugs are used with 3 or 4 pin adapters (not supplied) to molex (supplied) there is no third wire for speed info back to MB and there is no fourth wire for PWM fan control. They all hook to PSU via Molex and will provide a lot of air movement.
