Hey everyone so yesterday i upgraded my Unraid from i7 4790k to AMD ryzen 9 7900x, so first here's the list of parts i upgraded

 

Motherboard -- Asrock B650E Steel Legend Wifi

CPU -- Ryzen 9 7900X

RAM -- Adata DDR5 32GBx2 6000 CL30

 

Everyone thing is working just great but I'm not able to set temperature sensors on this AM5 Platform at first when i tried sensors cmd in the command line i got this response.

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +56.4°C  
Tccd1:        +37.4°C  
Tccd2:        +37.5°C  
 
amdgpu-pci-0d00
Adapter: PCI adapter
vddgfx:        1.44 V  
vddnb:         1.19 V  
edge:         +44.0°C  
PPT:           8.12 W 

then after some research on google i came to realize that some of these AM5 boards have Nuvoton IO Chips and you need to install drivers through community app store. I'm not sure my Asrock B650E Steel Legend Wifi board has this Nuvoton IO Chip but it looks like it does and i was like its not gonna hurt anything either i will get the reading if drivers work or i won't. So after installing the drivers now im getting this response from command line

and as you can see now i'm getting much more readings here but most of the Vcore reading are stuck to 0 volts so looks like its still not working as it should.
So please help me out here in getting proper temperature readings here.

amd ryzen chaged the cpu core temp in loger stuff the :

k10temp-pci-00c3 Adapter: PCI adapter Tctl: +56.4°C

is you cpu temp.

https://www.hwinfo.com/forum/threads/cpu-temp-sensors-explanation.5597/
-CPU (onboard sensor): This is either a temperature measured by a dedicated sensor on mainboard located inside the CPU socket (the external CPU temperature) or temperature obtained from internal CPU thermal sensor (i.e. DTS = Digital Thermal Sensor).

-Core Max: The maximum temperature among all cores in the CPU.

-CPU (Tctl): This is the T_control temperature available on AMD CPUs only. On several generations before Zen (Ryzen), this is not a reliable representation of the temperature. On AMD Zen series this is the temperature used to control cooling and is a fixed offset from the real CPU temperature. Offset is used mostly on X-series and some Threadripper CPUs; in such case two values are shown: Tctl and Tdie. If no offset is used, then only a single value is shown as Tctl/Tdie, which equals the real temperature.

-CPU (Tdie): This value is shown in case the CPU uses an offset from Tctl and represents the real temperature (Tdie = Tctl - Tctl_offset).

-CPU Package: Shown on Intel CPUs represents a 256-millisecond average value (calculated by CPU) of the hottest temperature sensor within the CPU package.

-CPU Package (TSI): Available on pre-Zen AMD CPUs is the CPU temperature obtained via TSI interface.

-Core #n (n=any number): Actual temperature of a particular CPU core.

-CPU IA Cores: Maximum temperature among all computing (x86) cores in CPU (so part of CPU except Uncore and Graphics logic).

-CPU GT Cores: Temperature of the integrated graphics part of CPU (if present).

There a whole thing due to how amd chagned ryzen temp sensors...
