Jumper Settings
Fan Connectors(FAN1/FAN2/FAN3/FAN4): The 5-pin
connector is for connecting the CPU fans. It comes
with the smart fan feature by which the fans could
be monitored and turned on when the temperature
exceed the set threshold. Connect CPU fans to
FAN1and FAN3, and connect auxiliary fans to FAN2
and FAN4.
Fan Connectors(FAN5): The 3-pin connector is for
connecting the chassis fan.
PCIe Connectors(PCIEC4/PCIEC3/PCIEC1/PCIEC2): It is
for connecting the expansion cards which might be
an Ethernet card or a RAID card. These PCIE sockets
oers a variation of PCIe lanes as listed below.

PCIEx8 Connector running at PCIEx8 mode
(PCIEC1,PCIEC2): to be connected to the front Ethernet
module. The jumper J31 can be used to select the
PCIe mode of these two connectors and jumper J32
can be used to select the order of the signal. Note
that with Ivy Bridge CPU, the PCIE also upgrades to
PCIe 3.0 standard (currently PCIe 2.0).
