ASUS P5LD2 2-29
9. CPU, Chassis, and Power Fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN1, CHA_FAN2, PWR_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 supports the ASUS Q-Fan feature.
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!
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 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.
