6. CPU, Chassis and Power Fan Connectors
(3-pin CPU_FAN1, CHA_FAN1)
The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a
total of 1A~2.22A (26.64W max.) at +12V. 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!
7. Chassis intrusion connector (4-1 pin CHASSIS1)
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.
