This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no):

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.

^Thanks @wistler_mb, @samoht, that's at least an announcement.

So if we know from the link of @Mister00X about the unification of the values Tdie and Tctl in certain models and sensors can't determine anything further in your case, then you have to use the Tctl value accordingly in Conky, the bar, etc., as the case may be.

The one with hwmon is appropriate where it is about not keeping the CPU busy by execi commands all the time, cue laptops, and to save a little CPU.

By the way, the '$' is my mistake, because the command does not need root.   
I hope all clarities are removed.

[samoht]

I am stubborn and out of curiosity: 
I do not understand, why inxi -s shows some temperatures with kernel 14, and no temperatures at all with kernel 15?

$ inxi -s
Sensors:   System Temperatures: cpu: 40.0 C mobo: N/A gpu: amdgpu temp: 31.0 C
           Fan Speeds (RPM): N/A

versus

$ inxi -s
Sensors:   Message: No sensor data found. Is lm-sensors configured?

[Mister00X]

I assume for the same reason why htop does not display temperatures for me anymore which I think is that those application depended on k10temp or sensors providing them with the temperature Tdie. Now with Tdie being non existent on systems where its identical to Tctl those applications are looking for the wrong variable, are unable to find it and display an error or in case of htop N/A.

[samoht]

Thanks, @Mister00X, you opened my eyes,

My fault: I neglected - did not understand or had forgotten your previous posts 

So I have now also tested it on my ryzen desktop PC Tdie is missing on the 5.15.1 Kernel too and with it the temperatures in htop.

Edit: This appears to be intended though according to https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/hwmon/k10temp.c?id=02a2484cf8d17a2acf3b9b151147bafaa55ad38c

Unfortunately, @jyp's statement seems to be true:

To say the least, it seems that, on amd ryzen, temperatures monitoring is not very reliable.

Thanks to all for comments,
Greetings,

@Mister00X,
I didn't know that htop can also be used to monitor temperatures. Only through man htop I have now noticed. Thanks for that.
My programs for this were always glances or bpytop. But you also need sensors.   

@jyp,
thanks for your details.

With hwmon you could monitor 6 temperature values on your system:   
- 2 SSD (nvme), but probably not worth it because they don't get hot.
- CPU (k10temp)
- MB (probably asus)
- wireless module (iwlwifi_1)
- battery (hidpp_battery_0)
- graphics card (amdgpu)

A nice place to start for the whole problem is the still up-to-date wiki of my friend Sector11.

And, last but not least, the temperatures of the WesternDigital hard disks can certainly be read out with hddtemp   , although that is no longer true either.

hddtemp (0.3-beta15-54) unstable; urgency=medium

  hddtemp has been dead upstream for many years and is therefore in a minimal
  maintenance mode. It will be shipped in the Debian Bullseye release, but
  will not be present in the Debian Bookworm release.

  Nowadays the 'drivetemp' kernel module is a better alternative. It uses the
  Linux Hardware Monitoring kernel API (hwmon), so the temperature is returned
  the same way and using the same tools as other sensors.

  Loading this module is as easy as creating a file in the /etc/modules-load.d
  directory:

    echo drivetemp > /etc/modules-load.d/drivetemp.conf

@unklarer

Thank you for the link; I will carefully read that.
Also, hwmon needs to get acquainted with.

^You're welcome.
I'm happy to help.
