Fan Headers - Supermicro Super X7SPA-L User Manual

Fan Headers

The X7SPA-L/X7SPA-H/X7SPA-HF has
two fan headers. Fan1 is the CPU fan and
Fan2 is for the system cooling 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.
(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 on the
same board. Refer to the table on the right
for pin definitions.
Note: The speeds of 4-pin (PWM)
fans are controlled by Thermal Man-
agement via BIOS Hardware Moni-
toring in the Advanced Setting. (The
default setting is Disabled.)
