8.CPU, System, and Auxiliary fan connectors (3-pin CPU-FAN, SYSTEM-FAN, AUX-FAN)

The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan cables to the fan connectors on the motherboard, making sure that the black wire of each cable matches the ground pin of the connector.
