How to make sense of the "sensors" output?

us flag

If I run the command sensors on my PC, this is the output I get:

hp_vendor-isa-0000
Adapter: ISA adapter
CPU FAN:        0 RPM

amdgpu-pci-0300
Adapter: PCI adapter
vddgfx:      643.00 mV 
vddnb:       768.00 mV 
edge:         +46.0°C  
PPT:           0.00 W  

BATT-acpi-0
Adapter: ACPI interface
in0:          13.07 V  
curr1:         0.00 A  

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +48.2°C  

nvme-pci-0200
Adapter: PCI adapter
Composite:    +32.9°C  (low  =  -0.1°C, high = +83.8°C)
                       (crit = +84.8°C)
Sensor 1:     +32.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +34.9°C  (low  = -273.1°C, high = +65261.8°C)

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +48.0°C  (crit = +113.0°C)
temp2:         +0.0°C  (crit = +128.0°C)
temp3:        +35.0°C  (crit = +128.0°C)
temp4:        +38.0°C  (crit = +128.0°C)
temp5:        +28.0°C  (crit = +55.0°C)
temp6:        +40.0°C  (crit = +128.0°C)

What are the various temperatures mentioned here? Which of these is/are my CPU temperature/s?

Try installing psensor as it is useful GUI version, does not harm and is easy to remove https://linuxhint.com/install-and-configure-psensor-sensor-monitor/

@darth_epoxy this doesn't give me any new information. It displays the same data (with the same labels) in a window :(

Do you know you to get to the Synaptic Package Manager? Go there and search for psensor then install it that way. It's a GUI application and mine displays each of my 4 CPU cores separately with the temperatures.

I can explain what the output means.

CPU FAN:        0 RPM

shows the CPU fan speed.

amdgpu-pci-0300
Adapter: PCI adapter
vddgfx:      643.00 mV 
vddnb:       768.00 mV 
edge:         +46.0°C  
PPT:           0.00 W

shows amdgpu sensors: voltage, temperature and some PPT (I don't know what it is), probably it is power consumption of some sort.

 BATT-acpi-0
Adapter: ACPI interface
in0:          13.07 V  
curr1:         0.00 A

shows the battery data: voltage, and current amperage.

k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +48.2°C

This should be the CPU temperature.

nvme-pci-0200
Adapter: PCI adapter
Composite:    +32.9°C  (low  =  -0.1°C, high = +83.8°C)
                       (crit = +84.8°C)
Sensor 1:     +32.9°C  (low  = -273.1°C, high = +65261.8°C)
Sensor 2:     +34.9°C  (low  = -273.1°C, high = +65261.8°C)

These are your NVME disk temperatures.

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +48.0°C  (crit = +113.0°C)
temp2:         +0.0°C  (crit = +128.0°C)
temp3:        +35.0°C  (crit = +128.0°C)
temp4:        +38.0°C  (crit = +128.0°C)
temp5:        +28.0°C  (crit = +55.0°C)
temp6:        +40.0°C  (crit = +128.0°C)

These are temeratures reported by ACPI. The first one is most likely the CPU one.

Thank you! What I read about the `tctl` temperature is that [it isn't necessarily a physical temperature](https://www.kernel.org/doc/html/v5.12/hwmon/k10temp.html#:~:text=It%20is%20measured%20in%20degrees,platform%20to%20control%20cooling%20systems.). I did need help with regard to the ACPI temperatures. Is there any documentation regarding what these temperatures correspond to?

Only the vendor knows what are these temperatures. `Tctl` should be the CPU temp.
I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
