Fan Headers
This motherboard has eight system/
CPU fan headers (FAN 1~FAN 8) on the
motherboard. All these 4-pin fans head-
ers 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 Monitoring in
the Advanced Setting in the BIOS. (See
Chapter 4 for more details.) See the table
on the right for pin denitions.
