Fan Headers
The X7SPE-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. (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.) 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.
