Motherboard: H470M-ITX/ac
BIOS: American Megatrends ver: P1.20 date: 05/18/2020
System: Linux Mint 20 Ulyana base: Ubuntu 20.04 Kernel: 5.4.0-54-generic x86_64 bits: 64 compiler: gcc v: 9.3.0

Here's a picture of the Hardware Page of the Advanced BIOS Settings:
https://drive.google.com/file/d/1RLgIsVHbYrNdZDwpGCqHEXxlqCfgxXSb/view?usp=sharing

The BIOS shows:
2 temperature Sensors
CPU Temp
M/B Temp

3 Fan Sensors
CPU Fan1
Chassis Fan1
Chassis Fan2

5 Voltage Sensors
CPU Vcore Voltage
PCH Voltage
+ 12.00V
+ 5.00V
+ 3.30V

The Linux Kernel Driver (5.4.0-54 is the latest version) decodes the Super I/O Chip used on the H470M-ITX/ac as a Nuvoton nct6798. I have tried everything I could think of to try to get a datasheet or info on the nct6798. On the Nuvoton website it's like the chip doesn't exist.

Here is the lm sensors report for my H470M-ITX/ac.

in0:                   656.00 mV (min = +0.60 V, max = +1.00 V)
in1:                     1.02 V (min = +0.95 V, max = +1.05 V)
in2:                     3.47 V (min = +0.00 V, max = +0.00 V) ALARM
in3:                     3.46 V (min = +3.30 V, max = +3.65 V)
in4:                     1.02 V (min = +0.00 V, max = +0.00 V) ALARM
in5:                   144.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in6:                   128.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in7:                     3.47 V (min = +3.30 V, max = +4.08 V)
in8:                     3.22 V (min = +3.14 V, max = +3.47 V)
in9:                   512.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in10:                   80.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in11:                   56.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in12:                    1.04 V (min = +0.00 V, max = +0.00 V) ALARM
in13:                  152.00 mV (min = +0.00 V, max = +0.00 V) ALARM
in14:                  776.00 mV (min = +0.00 V, max = +0.00 V) ALARM
fan1:                  1105 RPM (min =    0 RPM)
fan2:                  1240 RPM (min =    0 RPM)
fan3:                     0 RPM (min =    0 RPM)
fan4:                     0 RPM (min =    0 RPM)
fan5:                     0 RPM (min =    0 RPM)
fan7:                     0 RPM (min =    0 RPM)
SYSTIN:               +111.0°C (high = +36.0°C, hyst = +35.0°C) sensor = thermistor
CPUTIN:                 +30.0°C (high = +36.0°C, hyst = +35.0°C) sensor = thermistor
AUXTIN0:               +110.5°C    sensor = thermistor
AUXTIN1:               +113.0°C    sensor = thermistor
AUXTIN2:               +114.0°C    sensor = thermistor
AUXTIN3:               +38.0°C (high = +36.0°C, hyst = +35.0°C) ALARM sensor = thermistor
PECI Agent 0:           +31.5°C (high = +36.0°C, hyst = +35.0°C)
                                 (crit = +100.0°C)

in0 to in14 are the chips voltage inputs. I need to know which of those inputs are actually being used for the 5 Voltage Sensors the BIOS actually reads:
CPU Vcore Voltage
PCH Voltage
+ 12.00V
+ 5.00V
+ 3.30V
      
The fan inputs are not a problem but if anyone has some guidance for the temperatures that would be great.

Once i know how to map the inputs properly I can write a user config file to correct the way the kernel reports the sensor data.

Thanks in advance for taking the time to look this request for help over!
