Fan Connections
There are two fan connections, the system fan and the CPU fan. The fan speed
can be detected and viewed in the
PC Health Status section of the CMOS Setup.
Both 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.
