Fan Connections
There are five fan connections on the motherboard. The fan speed can be
detected and viewed in the
PC Health Status section of the CMOS Setup. The
fans are automatically turned off after the system enters S3, S4 and S5 mode.
Note that the CPU fan cable
can be either a 3-pin or a
4-pin connector. Connect a
3-pin connector to pins 1,
2, and 3 on the
motherboard connector.
