Speaker Connector (J22, pins 1-7)
This 4-pin connector connects to the case-mounted speaker.
2.5.11 CPU Cooling Fan Connector (J5)
This connector supports a CPU cooling fan of 500mAMP (6WATT)
or less. Orient the fan 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 maybe
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 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 if these pins are incorrectly used.
These are not jumpers. Do not place jumper caps over these pins!
