• The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan
power.
• Only the 4-pin CPU fan and 4-pin chassis fan support the Q-Fan feature.
2. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1/2)
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.
3. 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.
