Chassis intrusion connector (4-1 pin Chassis)
This connector is for a chassis-mounted intrusion detection sensor or switch. Connect

one end of the chassis intrusion sensor or switch cable to this connector. The chassis

intrusion sensor or switch sends a high-level signal to this connector when a chassis

component is removed or replace. The signal is then generated as a chassis intrusion

event.

By default, the pin labelled “Chassis Signal” and “Ground” are shorted with a jumper

cap. Remove the jumper cap only when you intend to use the chassis intrusion

detection feature.

CPU, Chassis, and Power Fan connectors (4 pin CPU_FAN, 3-pin CHA_FAN,

3_pin PWR_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, 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.

Only the CPU FAN supports ASUS Q-Fan.
