No, this isn't possible (at least not currently.) libsensors has now
way to know which chip is on what board on a given system. It could
check the DMI IDs but this could lead to false positives on some
motherboards / graphics cards combinations for example. Plus we have no
syntax to express this in the sensors3.conf format anyway.

We do already gather known motherboard configuration files, see:
http://www.lm-sensors.org/wiki/Configurations
http://khali.linux-fr.org/devel/lm-sensors/
If you have more, feel free to send them to the list and we'll add
them, or we can create a wiki account for you and you add them yourself.

These aren't meant to go to the default sensors3.conf file, we used to
do that years ago and this resulted in a huge default configuration
file which took long to parse and was a pain to maintain.

The missing piece now is a script that would check the DMI data of the
motherboard, look for a suitable configuration file and download it
to /etc/sensors.d semi-automatically. This could be integrated into
sensors-detect or made a separate script. This has been discussed in
the past already, some implementations have even been floating around.
Now it's really a matter of someone taking the time to integrate it all
properly.
