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.
