8. CPU , power, and chassis fan connectors (4-pin CPU_FAN, 3-pin
PWR_FAN and 3-pin CHA_FAN)
The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.) or
a total of 1 A ~ 3.48 A (41.76 W 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.
Only the CPU_FAN connector support the ASUS Q-Fan feature.
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!

9. 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 “GND” are shorted with
a jumper cap. Remove the jumper caps only when you intend to use the
chassis intrusion detection feature.
