9. CPU and system fan connectors (4-pin CPU_FAN1/2, REAR_FAN1/2,
FRNT_FAN1/2)
The fan connectors support 3-pin or 4-pin cooling fans of 350 mA ~ 740 mA
(8.88 W max.) or a total of 2.1 A ~ 4.44 A (53.28 W max.) at +12V. Connect
the fan cables to the fan connectors on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufficient air
flow inside the system may damage the motherboard components. These are
not jumpers! Do not place jumper caps on the fan connectors!
See "Section 4.3 Switch" to get detailed information about DIP switch setting for
4-pin or 3-pin fan cables.
