Chapter 2: Hardware information

9. CPU, chassis, and power fan connectors

(4-pin CPU_FAN, 3-pin CHA_FAN1-3, 3-pin PWR_FAN)
The fan connectors support cooling fans of 350 mA~2000 mA (24 W max.)

or a total of 1 A~7 A (84 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.

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 and CHA-FAN 1-2 connectors support the ASUS Q-FAN 2

feature.

10. 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 pin 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.
