CPU temperature reading are not updating

Support
1

Hello, I wanted to know the teperature of my CPU so I ran sensors-detect and just picked the default YES options. I ended up with two sensors which stay at said temperatures and do not change a bit so I am guessing something is wrong here. Also, btop++ doesn’t recognise the existence of those sensors at all and doesn’t show them.

sensors returns this:

So, what’s happening here?
Thanks

Hello,
Each sensor for each CPU physical core have their own physical location an do their own reading. If there is a air loop around that, the reading will differ. In most cases the CPU0 will run hotter than CPU1 …
Or is that you want to say that there is no change of the temperatures while the CPU is in LOAD vs when is in IDLE?

Please edit your topic title accordingly.

Please refrain from using so-called “textspeak”, “netspeak”, “leetspeak” and all other forms of internet slang.

EDIT: Thank you for editing your topic titile. :+1:

I am sorry that my question was unclear. I am saying that I did not see any other number than those two no matter what is happening, no matter the CPU usage.

5

Are the k10temp and it87 modules are loaded?
Did you run sudo sensors-detect at any point?

6

I have run sensors-detect, selecting the suggested. k10temp and it87 are not loaded. So that’s the problem.

7

Try
watch sensors
to update values every 2 secs.

8

Yes, I know about that, the problem is that there the temperatures do not chage between idle and load.
