The header supports Serial
Link interface for onboard
SATA connections.
PSU SMBus monitors the
status of the power supply, fan
and system temperature.
Please connect the CPU fan
cable to the connector 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
successfully even without the
fan speed control function.
If you plan to connect a
3-Pin CPU fan to the CPU
fan connector on this
motherboard, please connect
it to Pin 1-3.
*
For more details, please refer to the
Cooler QVL list on the ASRock Rack
website.
Please connect the fan cables to
the fan connectors and match
the black wire to the ground
pin. All fans supports Fan
Control.
