11)CPU Fan, Power Fan, and Chassis Fan Connectors (CPU_, PWR_, CHA_FAN)

Three fan connectors support cooling fans of 350mA (4.2 Watts) or less. Orient the fans so that airflow flows across the onboard heat sinks instead of expansion slots. The fan wiring and plug vary depending on the type employed. Connect the fan cable to the connector, ensuring that the black wire matches the ground pin. (Use the “Rotation” signal only with a specially designed fan with a rotation signal. You can monitor the Rotations Per Minute (RPM) using ASUS PC Probe (see 5. Software Support).

WARNING! Make sure to connect the fan cables to the fan connectors. Lack of sufficient airflow within the system could cause damage to the motherboard. These are not jumpers, do not place jumper caps over these connectors!
