7. 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. +5VSB_MB Chassis Signal GND CHASSIS ® P4C800 P4C800 Chassis Alarm Lead (Default) 8. CPU, Chassis, and Power Fan Connectors (3-pin CPU_FAN, PWR_FAN, CHA_FAN) 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! 2-26 GND +12V Rotation PWR_FAN CPU_FAN Rotation +12V GND ® CHA_FAN P4C800 GND +12V Rotation P4C800 12-Volt Fan Connectors Chapter 2: Hardware information
