Function: Power connectors for CPU and system housing cooling fans.
Description: There is one CPU cooling fan connector and two system-
housing cooling fan connectors on the motherboard. All the connectors
are 3-pin headers. Both the CPU and system fan connectors support fan
speed monitoring. A temperature monitor detects the CPU and internal
system temperatures, which are displayed in the PC Health section of the
CMOS Setup Utility. You can set a system shutdown temperature in that
section that will automatically shut down the computer to protect the
CPU if it reaches one of the three temperature options listed.
More Information: Please see the PC Health Status section of "Config-
uring the CMOS Setup Utility"in Chapter 5 for information.
