CPU Temp in Linux

Hi All.

I received my Bolt last night. I have been watching the temps, because of some of the problems I've seen in the forums. My temperatures, have been great, but I realized that lm_sensors doesn't say CPU temp. I was assuming the K10temp was CPU, and it does go up if I run stress cpu hog threads. Here is a screenshot of my sensors - which one is CPU? Thanks.

 

interested in the same, it seems the k10 (cpu?) and amdgpu-pci :: temp1 (gpu?) run about the same temp when i was doing a 4 thread stress test. it makes sense as they are a single package i suppose.
is there value in monitoring separately? or will they always be roughly the same

 

I believe the first sensor is in the Intel WiFi card (it seems to run hotter than the non-stressed CPU), the second is the power adapter, the third is the GPU and last is the CPU. But to be honest I am not 100% sure.

 

Hello @Andy Carlson ,

would you please tell us which software you are using to check the cpu temperatures? I am using and have to use Ubuntu 18.04 ...
I tried lm-sensors, but it didn't find any sensors.

Cheers,

DJVT

 

I used lm_sensors also, but it was on Fedora.

 

@DJVT Just use more recent kernel and you will be able to access ivi sensors;

Code:

Thank you @Zgembo,

unfortunately I am tied to Ubuntu 18.04 LTS and Kernel 5.0 because of some software and hardware I am using.

Update, acpi works on 18.04 with 5.0 Kernel:

$ sudo apt install acpi
$ acpi -t
Thermal 0: ok, 10.0 degrees C
Thermal 1: ok, 46.5 degrees C

idk what Thermal 0 is though. It is 10°C constantly, so probably misinterpreted data...
