[RESPONDED] New 12th gen overheating on light usage (Ubuntu 22.10)

Hi!

I just got a 12th gen with an i7 processor. I installed Ubuntu 22.10 on it, but have noticed the fan kicks on during light usage (web browsing mostly), and even sometimes when suspended.

I checked the core temperatures and they were running in the 50-70 degree range during these times.

Adapter: ISA adapter
Package id 0:  +72.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +70.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +72.0°C  (high = +100.0°C, crit = +100.0°C)
Core 8:        +64.0°C  (high = +100.0°C, crit = +100.0°C)
Core 12:       +63.0°C  (high = +100.0°C, crit = +100.0°C)
Core 16:       +57.0°C  (high = +100.0°C, crit = +100.0°C)
Core 17:       +57.0°C  (high = +100.0°C, crit = +100.0°C)
Core 18:       +57.0°C  (high = +100.0°C, crit = +100.0°C)
Core 19:       +57.0°C  (high = +100.0°C, crit = +100.0°C)
Core 20:       +52.0°C  (high = +100.0°C, crit = +100.0°C)
Core 21:       +52.0°C  (high = +100.0°C, crit = +100.0°C)
Core 22:       +52.0°C  (high = +100.0°C, crit = +100.0°C)
Core 23:       +52.0°C  (high = +100.0°C, crit = +100.0°C)

But there doesn’t seem to be anything to explain them. The system monitor dialogue was showing very low CPU usage (though uneven, one core might be at 50% while most were at 0%).

I tested it on a high load by opening a 45MB CSV file (I do know how to have fun!) which preformed fine but cause multiple cores to shoot to 100 degrees.

Any idea what my issue is?

Hello @Samuel_Dyck happy to assist, may we know what kernel you are using on Ubuntu 22.10? as we would recommend using kernel 5.19, do let us know how that goes

3

I’m on 5.19.0-35-generic

4

Ah alright, have you
Updated to the Latest Firmware ? let us know if you already did.

5

How high are your CPU clocks during this time?

6

Thanks! There doesn’t seem to be an instructions on how to do that anywhere online, or how to even check if you have most up-to-date firmware. However I followed all the instructions for how to set up Ubuntu on the Framework guide

It’s running quiet right now. Tempreture is:

Package id 0:  +43.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +42.0°C  (high = +100.0°C, crit = +100.0°C)
Core 4:        +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 8:        +35.0°C  (high = +100.0°C, crit = +100.0°C)
Core 12:       +40.0°C  (high = +100.0°C, crit = +100.0°C)
Core 16:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 17:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 18:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 19:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 20:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 21:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 22:       +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 23:       +39.0°C  (high = +100.0°C, crit = +100.0°C)

Core speed is:

cpu MHz         : 1138.862
cpu MHz         : 2500.000
cpu MHz         : 2500.000

cpu MHz         : 2500.000
cpu MHz         : 1036.558
cpu MHz         : 2500.000
cpu MHz         : 2500.000
cpu MHz         : 2500.000
cpu MHz         : 1175.389
cpu MHz         : 2500.000
cpu MHz         : 2500.000
cpu MHz         : 2500.000
cpu MHz         : 2500.000
cpu MHz         : 2500.000

When it starts to act up again I’ll post new clock speeds, but hopefully this is a useful baseline

The only BIOS update is a beta BIOS update as of right now for 12th gen see here for details 12th Gen Intel Core BIOS 3.06 Beta you cannot downgrade from 3.06 beta → 3.04 BIOS if I remember right so consider that.

Regarding the clocks my guess is that the clocks are spiking in these light loads and the heat output with it. It is something that I noticed with my 11th gen and now I power limited the CPU until I need the extra resources.

You might want to validate the thermal system is working as expected by comparing your system to others with benchmarks, there are several user benchmark post on the forums and even an official FW one.

Ok, just got home for lunch. Computer was suspended but fan was running loud

Core temps:

And what is top saying?

Also would be nice to have the output of free -m.

It’s also worth noting that the overheating is very inconsistent. I’ve opened the same massive spreadsheets as before earlier today without issue

13

I’m not smart enough to interpret benchmarks in a meaningful way, but here’s what I ran. The computer was running hot prior and during this test

14

Do you have auto update enabled?

15

Only for security updates. But that shouldn’t be the issue if the computer can run hot while suspended

16

Sorry, Just confirming, you have updated to the latest firmware?
also can you post temp figures after hibernation? thanks

@Samuel_Dyck the idea with the benchmark was just to check for any large disparity which could indicate a cooling system issue. Looking at your results I don’t see anything to indicate an issue there plus your idle temps look good.

18

My point was that unless you are explicitly suspending the laptop background processes may be preventing it. Hence your unexpected temps.

19

It’s hard to say. Nowhere could I find documentation on how to do that for Ubuntu (officials guide just says to search the community forums for distro-specific guidance, but couldn’t find any)

I’ll let it hibernate for a bit and see how that goes

20

I thought I had explicitly hit suspend but I’ll try turning it off
