Fan Headers
This motherboard has six system/CPU
fan headers (Fan 1~Fan 6, Fan A/Fan B)
on the motherboard. All these 4-pin fans
headers are backward compatible with
the traditional 3-pin fans. However, fan
speed control is available for 4-pin fans
only. The fan speeds are controlled by
Thermal Management via Hardware Mon-
itoring in the Advanced Setting in BIOS.
(See Chapter 5 for more details.) See the
table on the right for pin denitions.
