5. CPU and chassis fan connectors (4-pin CPU_FAN, 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. CPU_FAN CPU FAN PWM CPU FAN IN CPU FAN PWR GND P8B75-M LE CHA_FAN1 GND +12V Rotation P8B75-M LE fan connectors 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! • The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power. • Only the 4-pin CPU fan supports the ASUS Fan Xpert and Q-Fan 2 feature. 6. 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.
