7) Power Fan, CPU Fan, and Chassis Fan Connectors
The three fan connectors (PWR_FAN, CPU_FAN, CHA_FAN) 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 sink(s) instead of the expansion slots. The
fan wiring and plug may vary depending on the fan manufacturer. The red wire
should be positive while the black should be ground. Connect the fan plug to the
board taking into consideration the polarity of the connector.
NOTE: Use the “Rotation” signal only with a specially designed fan with a rotation
signal. You can monitor the Rotations Per Minute (RPM) of the fans using the
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.
8) USB Header (10-1 pin USBPORT)
If the USB port connectors on the back panel are inadequate, one USB header is
available for two additional USB port connectors. Connect the USB header to a
2-port USB connector set and mount the bracket to an open slot in the chassis.
(The USB connector set is optional and does not come with the motherboard
package.)
