extremely high CPU temperature

[beaverbusy]

Hi all. Fresh install of clear linux. Doing any minor activity (firefox, editing files in terminal etc) the CPU temperature raises very fast up to 85C. Same machine under Arch linux/fedora/nixos, the temperature stays below 50C no matter what. Fan is blowing more than on other distros even when doing nothing.
Tried both standard and LTS kernel. Tried stopping thermald. Both didn't help. Any suggestions?

Any chance you can run powertop --html And collect the output file?

here two measurments under i3 and gnome. They are html files, but I renamed them to .txt as git wouldn't let me attach it otherwise.

powertop.txt
powertop3.txt

Are you using the same video adapter under the other OS's? Do you have the proprietary NVIDIA drivers installed in the other OS's?

[beaverbusy]

yes, I'm using nouveau driver under all the OSes. The lspci -k gives me the same list of drivers on all distros.
lscpi.txt

Only thing I can think of is that we set the CPU governor to performance by default. Maybe it's worth setting it back to powersave or whatever the value is under the other OS's. Honestly, I'm asking "for a friend", as well ;).

[fenrus75]

11.4% 20.9 Process [PID 1969] /usr/bin/NetworkManager

it kind of looks like NM is using 11% of cpu always?

can you check in "top" to see if there's processes with always high cpu utilization

if those exist that more than anything explains the high temp (more than cpu governors potentially, since those don't matter while idle)

Great, that lowered the temperature to 55C. Thanks. I used:
echo powersave > /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
to change the governor, but after an hour it went back to performance, and the Temp jumped up again.
Is there a way to make the change permanent?

[ahkok]

I don't think it should change back, unless you suspended or rebooted?

I ... was thinking through a boot option, but I can't find any governor specific kernel cmdline option to override this either. @fenrus75 ?

@ahkok @fenrus75 perhaps would be nice to either go powersave/auto the same way we do with thermald? (depending on battery device). I'm experiencing also high temps on a dell xps. Will test with powersave next.

It seems to depend on the machine: on my desktop there's no issue, on anther laptop (with bigger air vent) temp is ok too.
