Fan Headers
This serverboard has six system/CPU
fan headers (Fan 1-Fan 4, Fan A and
Fan B ) on the serverboard. 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 IPMI 2.0 interface.
See the table on the right for pin
defi nitions.
