7)CPU Fan, Power Fan, and Chassis Fan Connectors (CPU_FAN, CPU_FAN2, PWR_FAN, CHA_FAN)
The four fan connectors support cooling fans of 350mA (4.2 Watts) or less. Orient the fans so that the heat sink fins allow airflow to go across the onboard heat sinks instead of the expansion slots. The fan wiring and plug may vary depending on the fan manufacturer. Connect the fan cable to the connector making sure that the black wire matches the ground pin. (NOTE: 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 6. SOFTWARE REFERENCE).
WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers,
do not place jumper caps over these pins.CPU_FAN
