5. CPU and Chassis Fan connectors (4-pin CPU_FAN, 3-pin CHA_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, ensuring that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors. Only CPU Fan supports Q-Fan. R M3N78-EMH HDMI CPU_FAN CPU FAN PWM CPU FAN IN CPU FAN PWR GND CHA_FAN Rotation +12V GND M3N78-EMH HDMI Fan Connectors 6.
