Fan Header

The X8DTT-H series serverboard has one

fan header on the serverboard. This 4-pin

header is backward compatible with tradition-

al 3-pin fans, however, fan speed control is

only available for 4-pin fans. The fan speeds

are controlled by Thermal Management

via Hardware Monitoring in the Advanced

Setting in the BIOS. (The default setting is

disabled.) See the table on the right for pin

deﬁ nitions.
