Hum, no, the temperature measurements are handled the same way for each
winbond chip. And, if I trust the docs (from http://www.winbond.com/)
this is correct, wich one minor nit: the W83627HF may have only 2 sensors where
the W83781D/W83782D have 3. So in your outputs, one of the temps won't
make sense.
I say "may" because the doc isn't clear: some places talk about only
2 sensors, but in the registers description the registers for the third
sensors is there.

Maybe your motherboard has a weird sensors ?
