The fan connectors support 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!
