Internal Speaker Connector: CON1
This connector is used to connect the
built-in speaker
.
The CPUFAN1 (CPU fan) and SYS_FAN1 (system fan) support system
cooling fans with +12V that is controlled by PWM.
When connecting the wire to the three-pin head connectors, always note
that the red wire is the positive and should be connected to the +12V (that is
controlled by PWM), the black wire is Ground and should be connected to
GND. If the mainboard has a System Hardware Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage of the
CPU fan control.
Fan Power Connectors: CPUFAN1/SYS_FAN1
On-Board S-Video out Connector: JTV1
