This shows that PECI Agent 0 is supposed to be enabled.

^^
This value suggests that the second temperature sensor (the one creating
the alarm) is supposed to be the PECI source (which reports the CPU temperature
to the NCT6776), and that it is supposed to be used to control the speed
of the CPU fan.
^^
Fan control is in manual mode. Did you set this ?
It is quite unusual.

^^
00 here shows that the PECI source is not active, ie the CPU does not deliver
PECI data to the NCT6776. This explains the alarm.
Practical impact is probably limited as fan control is configured to be manual
anyway, but I wonder why PECI doesn't work on your board. PECI configuration
is identical to my Supermicro board.
