ASUS P5B Deluxe -1
7. CPU, chassis, power, and chipset fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2, 3-pin CHA_FAN3,
3-pin PWR_FAN; WiFi-AP Edition: 3-pin CHA_FAN4, 3-pin CHA_FAN5)
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 1-3 connectors support the ASUS Q-
FAN 2 feature.
• If you install two VGA cards, we recommend that you plug the rear
chassis fan cable to the motherboard connector labled CHA_FAN1
or CHA_FAN2 for better themal environment.
Never connect a USB cable to the IEEE 1394a connector. Doing so will damage
the motherboard!
You can connect the 1394 cable to ASUS Q-Connector (1394, red) first, and
then install the Q-Connector (1394) to the 1394 connector onboard.
