Fan Header
The X8DTT-H Series motherboard has a cool-
ing fan on the motherboard. This 4-pin fan
header is backward compatible with the tradi-
tional 3-pin fan. However, fan speed control is
only available for a 4-pin fan. 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.
