The fan connectors support cooling fans of 350mA~2000mA (24 W
max.) or a total of 1A~3.48A (41.76 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. Lack
of sufficient air flow inside the system may damage the
motherboard components. These are not jumpers! DO NOT place
jumper caps on the fan connectors!
• The ASUS Smart Q-Fan function is supported using the CPU fans
(CPU_FAN1, CPU_FAN2) connectors.
• The chipset fan is synchronized with the CPU fans.
