Fan Headers
The X7SBA has six fan connections
(Fan1 to Fan6). Fan6 is designated
the CPU Cooling Fan. Note: all these
fans are 4-pin fans. However, Pins
1-3 of the fan headers are backward
compatible with the traditional 3-pin
fans. The onboard fan speeds are
controlled by Thermal Management
under Hardware Monitoring in the
BIOS. When using Thermal Manage-
ment settings, please use all 3-pin
fans or all 4-pin fans on the mother-
board. Please do not use 3-pin fans
and 4-pin fans on the same board.
The default setting is "Disabled"
which will allow the onboard fans to
run at full speed. See the table on
the right for pin denitions.
