2. CPU, Chassis and Power Fan connectors (4-pin CPU_FAN, 3-pin CHA_FAN1,
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, 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. Insufcient air ow 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 and CHA_FAN1 connectors support the ASUS Q FAN 2 feature.
3. 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 replaced. The signal is then generated as a chassis intrusion
event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with a jumper
cap. Remove the jumper caps only when you intend to use the chassis intrusion
detection feature.
