This is a 120mm high power fan that can be integrated over The TV Shield PRO back vents to provide superior airflow. This fan provides additional heat dissipation by extracting hot air out of the top of the enclosure dissipating it out through the upper back vents of The TV Shield PRO. The fan kit includes a 20" lead cable and hardware and is meant to be placed over the leftmost upper back vent. If installing multiple fans over several vents you will need to purchase wire extenders to reach the integrated fan module (plug) already installed in The TV Shield PRO. Contact us for wire extenders if installing multipe fans.
