Fan Headers
This serverboard has six system/
CPU fan headers (Fan 1~Fan 5, Fan
A). All are 4-pin fans headers and
backward compatible with traditional
3-pin fans. However, fan speed con-
trol is available for 4-pin fans only.
The fan speeds are controlled by
Thermal Management via Hardware
Monitoring in the Advanced Setting
in the BIOS. (See Chapter 7 for more
details.) See the table on the right for
pin definitions.
