8. CPU, power and chassis fan connectors (4-pin CPU_FAN, 3-pin PWR_
FAN, 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 and CHA_FAN connector support the ASUS Q-Fan feature.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow
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.
