Fan Headers

The C2SBX/C2SBX+ has five chassis fan
headers (Fan1 to Fan5). Fan 1 is the CPU
Fan. Fan 2 to Fan 5 are system/chassis
fans. (Note: Pins 1-3 of a 4-pin fan header
are backward compatible with a traditional
3-pin fan.) See the table on the right for
pin definitions. The onboard fan speeds
are controlled by Thermal Management via
Hardware Monitoring in the Advanced Set-
. (
ting in the BIOS Note: Default: Disabled
When using Thermal Management setting,
please use all 3-pin fans or all 4-pin fans
on the motherboard.)
