Some pins of the W83792D chip can be used for different purposes. In
your case, the fan6 pin is indeed used for something different so the
w83792d kernel driver did not create an interface for that fan.
"sensors" should ignore missing interface files in this case, but the
version you have did not. This was fixed in CVS recently.

You may try to add an "ignore fan6" statement in your configuration
file.

Looks like a known bug, fixed in lm_sensors 2.9.2.

-48 degrees C is a typical value for unconnected thermal sensors. You
can probably just ignore that input ("ignore temp3").
