Plug the fan into the CPU_FAN header, and the pump into any of the other fan headers it will work fine.
The fourth pin is for digitally controlled fan speed, so if looking for a fan controller, you'd need a much more expensive model to controll the fans, Half the time Newegg doesn't even carry them, because they are hard to find, most people just use 3 pin fans for thee case, and allow the main board to controll the CPU fan.
