6. CPU, Chassis, and Power Fan Connectors
(3-pin CPUFAN1, CHASFAN1)
The fan connectors support cooling fans of 350mA~740mA (8.88W
max.) or a total of 1A~2.22A (26.64W 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. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
7. Smart Card Reader connector (14-1 pin SMARTCON1)
This connector accommodates a Smart Card Reader that allows you to
conveniently make transactions such as financial, health care,
telephony, or traveling services through a Smart Card user interface
software.
