Fan Headers
This motherboard has eight 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 Monitoring
in the Advanced Setting in the BIOS.
(See Chapter 4 for more details.) See
the table on the right for pin defi nitions
Chassis Intrusion
A Chassis Intrusion header is located
at JL1 on the motherboard. Attach an
appropriate cable from the chassis to
inform you of a chassis intrusion when
