Fan Headers

The C2SBA+II/C2SBA+/C2SBA/C2SBE has five chassis fan headers (Fan 1 to Fan 5). Fan 1 is the CPU Fan. Fan 2 to Fan 5 are system/chassis fans. (Note: Pins 1-3 of a 4-pin fan headers are backward compatible with the traditional 3-pin fans.) See the table on the right for pin definitions. The onboard fan speeds are controlled by Thermal Management via BIOS Hardware Monitoring in the Advanced Setting. (Note: Default: Disabled. When using Thermal Management settings, please use all 3-pin fans or all 4-pin fans on the motherboard.)
