III.INSTALLATION

9.Chassis Fan, CPU Cooling Fan, & Power Supply Fan Connectors (FANPWR) These connectors support cooling fans of 500mAMP (6WATT) or less. Orien- tate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan's plug to the board taking into consid- eration the polarity of the this connector. NOTE: The “Rotation” signal is to be used only by a specially designed fan with rotation signal.

WARNING: The CPU and/or motherboard will overheat if there is no air- flow 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.
