Hi lm_sensors-list.
I contacted Gigabyte-Support on this topic via:
http://www.gigabyte.de/support-downloads/technical-support.aspx
I think it is worth, that some of the lm_sensors-developer would ask
directly at the support for supporting data to develope a working driver.
This is what I got from them:

Dear Mr. Bruns,
Update:
Our hardware team did reply:
First, we don’t guarantee third party S/W performance.
Second, just found some info. of LM sensors on our MB that is confirmed
working, hope this can help the user:
http://www.spinics.net/lists/lm-sensors/msg42493.html
Third, we don’t know what exact info. or value LM sensors needs, so the
request is too rough.
So if user has trouble to use LM sensors on our MB, please suggest user
to contact LM sensors and ask their team to contact us.
In that way we can get a clearer image of the info. they need for
programming.
Thank you.
Thank you for emailing GIGABYTE.
We are delighted with your interest in our products.
We forwarded to our hardware team.
Will come back to you once they reply.
Regards
GIAGBYTE Team

Hi,
I have a Mainboard from Gigabyte which is this one:
GA-Z97X-Gaming G1 WIFI-BK
I am running the board with gentoo-linux and 3.18.3 Kernel
It has ITE 8620 onboard:

I try to use it like stated in the device overview as ITE 8728

Now the Problem:
The Board has the possibility to connect 5 Case Fans and 2 CPU Fans
I have 1 CPU-Fan and 3 Case Fans.
CPU-Fan has 4 power-lanes, case-fans have all 3 power-lanes
where 4 are possible
fan1 above in sensors-output is the same as SYS_FAN2, so a case-fan
fan2 above in sensors-output is the same as SYS_FAN3, so a case-fan.
I tried to stop the fans to see which one of the two shown by sensors
is which one in the hardware I have.
So one case-fan is missing and !!! CPU-Fan is missing here.
You could try to connect the cpu fan to the other cpu fan connector to see
if it shows up.
I also tried to apply this patch to the kernel:
http://www.spinics.net/lists/lm-sensors/msg43167.html
I then see in sensors the same output, but instead of
it8728-isa-0a30
I see
it8620-isa-0a30
The only real difference is to add support for the new ID, so this is
not surprising.
Besides the fan problem, the CPU temperature display is wrong as well.
So I would like to do tests for you te get a working
patch for ITE 8620E
From the above, I think we have to conclude that the 8620 isn't as close
to the 8728 as we would like, and that we do not have enough information
about the 8620 to add support for it to the kernel.
Unfortunately, the chip was made by ITE specifically for Gigabyte,
and neither ITE nor Gigabyte are likely to release the datasheet.
Unless someone steps up and provides the information we would need,
I see little chance that we will be able to make the necessary changes
to the driver.
