So, the board has a Winbond W83783G and your OS doesn't support this
chip. It should be pretty clear at this point that it's simply not
going to work, no matter what you put in sensors3.conf.

You either need to upgrade to a more recent OS, or backport the w83793
driver to your OS. The latter shouldn't be too difficult, I know a
number of people have done that already, as apparently boards with
Winbond W83793G chips are popular amongst RHEL 5 / CentOS 5 users.

If you don't know how to do this, you can try to find a kernel
developer who will do it for you. That could be me, if you have a piece
of hardware you no longer need and you wouldn't mind shipping it to me:

That's the nice thing with Supermicro: they provide all the technical
data one needs to refine the sensors configuration. With the above you
can write a perfect custom sensors3.conf file for your board. All you
have to do is cross-check the register addresses (named "offset" in the
above document) with either the driver source code or the datasheet.

This last feature we unfortunately do not support (yet).
