ASUS M2V 2-25
5. CPU, Power and Chassis Fan Connectors
(4-pin CPU_FAN, 3-pin CHA_FAN1, 3-pin CHA_FAN2 )
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!
