Fan Headers
The X7SBL-LN1/LN2 has six fan headers
(Fan1 to Fan6) including five chassis/sys
-
tem fan headers (Fan1 to Fan5) and one
CPU Fan (CPU Fan6). All these fan head-
ers support 4-pin fans. However, Pins 1-3
of the fan headers are backward compat-
ible 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.
Notes:
1. The Default setting is Disabled.
2. Please use all 3-pin fans or all
4-pin fans on the motherboard.
Please do not use 3-pin fans and
4-pin fans on the same board.)
