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.
