mount the fan onto the case, and plug the fan power into a fan header on the motherboard. If you do not have an available fan header on the motherboard then you will need a molex to fan power adapter, or a fan controller to plug into.
From what I can tell on the Newegg picture your motherboard seems to have 1 CPU fan header, and 1 case fan header. Refer to your owners manual, it will have a picture that points out where the fan headers are.
