6.
Speaker connector (4-pin SPEAKER)
The 4-pin connector is for the chassis-mounted system warning speaker. The speaker
allows you hear system beeps and warnings.
5. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1/2)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan of
maximum 1A (12 W) fan power.
