Fan Headers

The X8ST3-F/X8STE has five fan head- ers (Fan1 ~ Fan5). Fans 2~5 are system cooling fans. Fan 1 is used as a CPU fan. These fans are 4-pin fan headers. However, Pins 1-3 of the fan headers are backward compatible with the traditional 3-pin fans. The default setting is Disabled which allows the onboard fans to run at full speed. Refer to the table on the right for pin definitions.

Note: Please use all 3-pin fans or all 4-pin fans on a mother- board. Please do not use 3-pin fans and 4-pin fans on the same board.
