X7DA3+ User's Manual

Fan Headers

The X7DA3+ has eight chassis/system fan headers (Fan1 to Fan8), including two CPU Fans (Fans 7/8). (Note: Pins 1-3 of 4-pin fan headers are backward compatible with the traditional 3-pin fans). See the table on the right for pin defi nitions. (The onboard fan speeds are controlled by Thermal Manage- ment via BIOS Hardware Monitor in the Advanced Setting. Note: The Manufacturer Default is set to Dis- abled to allow the fans to constantly run at the full speed. When using Thermal Management setting, please use all 3-pin fans or all 4-pin fans on the motherboard.)
