Fan Headers
T h e P D S M L - L N 1 + / P D S M L - L N 2 + /
PDSML-E+ has six fan connections (Fan1
to Fan6). Fan6 is designated as the CPU
Cooling Fan. Note: all fans are 4-pin fans.
However, Pins 1-3 of the fan headers are
backward compatible with the traditional
3-pin fans. See the table on the right for
pin definitions. The onboard fan speeds
are controlled by Thermal Management
in the BIOS Hardware Monitoring Setting.
When using Thermal Management setting,
please use all 3-pin fans or all 4-pin fans
on the motherboard. Please do not use
both 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
the full speed.
