Front/baCk/Cpu/auX Fan ConneCtors

There are nine 3-pin fan connectors in the ServerBoard motherboard. Two fans are used

for CPU0 and CPU1; seven are for auxiliary power. These connectors support cooling fans

of 500mA (6W) or less. Depending on the fan manufacturer, the wiring and plug may be

different. Connect the fan’s plug to the serverboard with respect to the polarity of the fan

connector.

WARNING

The CPU and/or motherboard will overheat if there is not enough airﬂow across the CPU and

onboard heatsink. Damage may occur to the motherboard and/or the CPU fan if these pins

are incorrectly used. These are NOT jumpers, do NOT place jumper caps over these pins.

NOTE

* The “Rotation” signal can only be used with fans specially designed for the

rotation signal.

* Only fans connected to FRONT_FAN1, FRONT_FAN0, H0_FAN1, H0_FAN1,

H1_FAN0 and H1_FAN1 are monitored by the BIOS
