Summary0001443: Only partial support for Winbond W83627DHG, W83791D
DescriptionI have Asus Maximus Extreme motherboard.
There are 3 connectors for optional sensors and 3 connectors for optional fans.
All fan and sensor connectors are used.
Speeedfan always reports "0C" as temperature on 3rd optional connector (Winbond W83791D), while Asus tool and HW Monitor Pro reads temperature correctly.
Also HW Monitor Pro show 7 voltages on W83627DHG (Speedfan - only 3!), 7 volages on W83791D (Speedfan show none on them).
And no support for Analog Devices ADP3228 (Current and Power), but there are no support for current and power in Speedfan.

GPU Temperature is missing (Radeon HD4650).
TagsNo tags attached.

More info:
Temp3 on Winbond W83791D show "0C" or "1C". Mostly "0C".
Tried to set in "Advanced" "30" as temp offset for temp3, immediately after that Temp3 showed "-98". Set back offset to "0", Temp3 = "-128C". After a several seconds - Temp3 = "0C".
Reproduced several times with different offsets.
One time Temp3 showed right measure (36C) but only for a few seconds.

When voltages are not shown by SpeedFan, the reason is that the datasheet is incomplete or I can't understand how to decode them.
