X7DBi+ User's Manual

Fan Headers

The X7DBi+ has six chassis/system fan headers (Fan1 to Fan6) and two CPU Fans (Fans 7/8). (Note: Fans 5/6/7/8 are 4-pin fans. However, Pins 1-3 of these fan headers are backward compatible with the traditional 3-pin fans. *The onboard fan speeds are controlled by Thermal Management via BIOS Hardware Monitor in the Advanced Setting. Note: When using Thermal Management setting, please use all 3-pin fans or all 4-pin fans on the moth- erboard. (The Default setting for Fan Speed Control in the BIOS is Disabled.)
