the right for speaker pin defini-
tions. Note: The speaker connec-

Fan Headers
The X6DHT-G has eight fan head-
ers (Fan1 to Fan8). (*Note: Fans
5-8 are 4-pin fans. However, Pins
1-3 of the fan headers are back-
ward compatible with the tradi-
tional 3-pin fans.) See the table on
the right for pin definitions. (*The
onboard fan speed is controlled by
Thermal Management via BIOS--
Hardware Monitor in the Ad-
vanced Setting. Note: Default: Dis-
abled, When using Thermal Man-
agement setting, please use all 3-
pin fans or all 4-pin fans on the
motherboard. Please do not use 3-
pin fans and 4-pin fans on the
same board.)
