Fan Headers
The X8ST3-F/X8STE has ve 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 denitions.
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.
