Fan Headers

The X8DTG-DF has eight chassis/system fan headers (Fan1 to Fan8) on the motherboard. All these 4-pin fans headers are backward compatible with the traditional 3-pin fans. 3-pin fans do not support fan speed control. How- ever, fan speed control is 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 definitions.
