Sorry I forgot to reply to the list last time, adding it back...

Following the advice

This doesn't apply to the NCT6776. See in the output above, there is no
"div =" on the fan lines.
Maybe the document should be clarified.
I just did so [1], hopefully the updated document is clearer and users
will understand whether they have to read it or not.
[1] http://www.lm-sensors.org/changeset/6071
Do you know if is there any way to collect the right speeds as UEFI
values are good.
No idea. Check the motherboard documentation. If the fans are really
connected to the NCT6776, this may be a driver bug. BTW you said you're
using the w83627ehf driver from groeck, but there is a better driver
for the NCT6776 now:
https://github.com/groeck/nct6775
Guenter, maybe this driver should be listed at
http://roeck-us.net/linux/drivers/
so that users find it?
If the new driver doesn't help, maybe the fans are connected to another
monitoring chip.
Does the mean all the AMD FX CPU have the same issue? What to do? Is a
patch on the way?
There's no relation between fan speed monitoring and the CPU your
system is using.
Temperatures in the hardware area have a load of loose vocabulary.
I try to be accurate:
Could you confirm that CPUTIN is the temperature read by the sensor in
the socket of the motherboard called Tjunction?
I don't think so. AFAIK Tjunction refers to a temperature limit inside
the CPU, and it related to the digital thermal sensor in the CPU.
CPUTIN OTOH is an analog thermal sensor. As it is a thermistor in your
case, it is likely under the CPU, in the middle of the CPU socket.
Could you confirm that K10temp, temp1 is what AMD call Tctl (sliding
scale) accessible through D18F3xA4[CurTmp] register (from BIOS and
Kernel Developer's Guide)?
Yes, this is correct.
Could you tell me what is SYSTIN (system temp input) and AUXTIN
(auxiliary temp input)?
These are analog thermal sensor inputs. As already mentioned, AUXTIN is
apparently not used on your board, you can ignore it. SYSTIN could be
anywhere on the motherboard, we can't tell. Maybe the technical
documentation for your board has the information.
Are they in the list bellow?
I have no idea where this list comes from, so I can't really comment on
that, sorry. Other than:
TJunction is the temperature where the pins hit the board
TJunction is still a diode on the board, under the processor
This is completely wrong. At least this is not what the rest of the
world, starting with Intel technical documentation, refers to as
Tjunction.
The new document version is now clear to understand and moreover we know
why we don't need the divisor in some chips.
I installed the new driver. For around 15 minutes I had fan2 value
(about 1150 RPM).
I did some changes in the sensors3.conf file, then sensors -s, was OK.
After some try I have fan2 = 0 RPM. I did cold boot, reinstall driver,
reinstall lm-sensors, still 0 RPM.
I can't find why it's not working any more.
Any idea?
TJunction and vocabulary:
This term is for me as well the temperature of a PN/NP, etc junction in
a electronic component mainly used to calculate the radiator.
In the CPU/motherboard environment it seems to be the temperature at the
junction between CPU and motherboard, at the pins.
I had this info and I wrote the vocabulary list from the following link
http://www.overclock.net/t/1128821/amd-temp-information-and-guide/70
in the post #73
These are mails from AMD support so I suppose the definitions are good
at least for AMD.
However this other link is more like I use to know.
http://www.alcpu.com/forums/viewtopic.php?f=63&t=892
I will try to have again the fan value and let you know
