Fan Headers
The X8SIL/X8SIL-F has five fan headers (Fan1

~ Fan5). These fans are 4-pin fan headers.
		Pin Definitions
However, Pins 1-3 of the fan headers are		Pin#		Definition
backward compatible with the traditional 3-pin	1			Ground (Black)
fans. A fan speed control setting in the BIOS	2			2.5A/+16V
Hardware Monitoring section allows the BIOS				(Red)
	3			Tachometer
to automatically set fan speeds based on the
	4			PWM_Control
system temperature. 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 motherboard. Please
do not use 3-pin fans and 4-pin fans
