6. 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.

7. CPU, Chassis, and Power Fan Connectors
(3-pin CPU_FAN1, PWR_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!
