Fan Headers
The X8DTG-QF has ten chassis/system fan
headers (Fan1 to Fan10). Fan 7 and Fan 8
are CPU Fans. All these 4-pin fans headers
are backward compatible with the traditional
3-pin fans. Fan speed control is available for
4-pin fans but not supported by 3-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.
