7. CPU and Chassis Fan Connectors
(3-pin CPU_FAN, CHA_FAN)
The fan connectors support cooling fans of 350mA~740mA (8.88W max).
Connect the fan cables to the fan connectors on the motherboard, making sure
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. Lack of sufficient
air flow within the system may damage the motherboard components. These
are not jumpers! DO NOT place jumper caps on the fan connectors!
8. Chassis intrusion connector (4-1 pin CHASSIS)
This lead is for a chassis designed with intrusion detection feature. This
requires an external detection mechanism such as a chassis intrusion sensor
or microswitch. When you remove any chassis component, the sensor triggers
and sends a high-level signal to this lead to record a chassis intrusion event.
By default, the pins labeled "Chassis Signal" and "Ground" are shorted with a
jumper cap. If you wish to use the chassis intrusion detection feature, remove
the jumper cap from the pins.
