I have researched this and there does not seem to be any setting for this
in the bios. I can only see the current CPU-temp and the fan speed in the
The FAN-section in the manual says the following:
"CPU Fan and System Fan: CPUFAN and SYSFAN
The CPUFAN (CPU fan) and SYSFAN (system fan) run on +12V and maintain
system cooling. When connecting the wire to the connectors, always be
aware that the red wire is the Positive and should be connected to the +12V.
The black wire is Ground and should always be connected to GND.
FAN_MCM is a switch that is used by high-quality fans to monitor the system
temperature and will automatically adjust according to the environment."
Does this mean that it only runs based on a hidden, preset, threshold?
I have also set a cpu and chassi max temperature threshold (powerdown if
things get too warm I guess?) - but this should be unrelated?
Connecting the fan to a regular molex connector works, so problem is
"solvable", but as described when connected to the sysfan 3-pin
motherboard connector it stops running after boot is completed.
Thanks for your input.
