7)CPU and Chassis Fan Connectors (3-pin CPU_FAN1/2, CHA_FAN1/2)

These connectors support cooling fans of 860mA (10.3 Watts) or less. Orient 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 consideration the polarity of the connector.

NOTE: The “ Rotation” signal is to be used only by a specially designed fan with rotation signal. The Rotations Per Minute (RPM) can be monitored using Intel LDSM Utility (provided with certain models).

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.
