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. Insufcient air ow 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.
