9. CPU and chassis fan connectors (4-pin CPU_FAN and 3-pin CHA_FAN)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
Only the 4-pin CPU fan supports the ASUS Q-Fan feature.
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.
10. LPT connector (26-1 pin LPT)
The LPT (Line Printing Terminal) connector supports devices such as a printer. LPT is
standardized as IEEE 1284, which is the parallel port interface on IBM PC-compatible
computers.
