2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place
jumper caps over these headers and connectors. Placing jumper caps
over the headers and connectors will cause permanent damage of the
motherboard!
CPU Fan Connectors
Please connect the CPU fan
(4-pin CPU_FAN1)
cable to the connector and
(see p.8 No. 30)
match the black wire to the
ground pin.
(4-pin CPU_FAN2)
(see p.8 No. 23)
Though this motherboard provides 4-Pin CPU fan (Quiet Fan) support, the 3-Pin
CPU fan still can work successfully even without the fan speed control function.
If you plan to connect the 3-Pin CPU fan to the CPU fan connector on this
motherboard, please connect it to Pin 1-3.
Digital Input / Output Pin Header
(10-pin JGPIO1)
(see p.8, No. 6)
Chassis Intrusion Headers
This motherboard supports
(2-pin CI1, CI2: see p.8, No. 25)
CASE OPEN detection feature
that detects if the chassis cover
has been removed. This feature
requires a chassis with chassis
intrusion detection design.
