Please connect fan cables
to the fan connectors and
match the black wire to the
ground pin.
Though this motherboard
provides a 4-Pin CPU fan
(Quiet Fan) connector, 3-Pin
CPU fans can still work suc-
cessfully even without fan
speed control. If you plan to
connect a 3-Pin CPU fan,
please connect it to Pin 1-3.
Besides one default IEEE
1394 port on the I/O panel,
there is one IEEE 1394
header on this motherboard.
This IEEE 1394 header can
support one IEEE 1394 port.
