Tumbleweed, AMD Ryzen 5825U.
With CPU load of 2-10% the fan is constantly blowing, since the frequency is 3.85-4.25 GHz and does not fall, temp is around 64 degrees.
Starting Thunderbird the CPU utilization rises to 15-20%, freq is around 3.5 GHz and temp rises to 100 degrees. Notebook is getting hot.
Under Windows no such a problem al all, works fine does not heats up.
What could be the problem under Linux?
See all governor states on Mission Center screenshot:
It is showing that you’re using amd_pstate-epp.
I believe you need to add this to your kernel command line parameters.
amd_pstate=guided
I have’t changed anything… I will try to put it to kernel thrue Yast
BTW, kernel command line looks like:
splash=silent amd_pstate=guided resume=/dev/disk/by-uuid/52e999f7-7d2c-42ee-9471-76a08afd1957 quiet security=apparmor
Do you have the power-profiles-daemon package installed?
And it did change the governor to schedutil. You should be able to select powersave too.
AMD changed the scaling governor so many times that it was hard to keep track of. A lot of people were reporting that their CPU was running as fast as it could with no load. I’m not sure about how to configure a mobile CPU. But I do know it’s a combination of the correct amd-pstate driver and governor.
Do you have a hung application?
Here’s a lot of info about governors etc.
It gives you all of the commands to change and test things.
I don’t understand why your CPU is running wide open when using
balanced and powersave.
power-profiles-daemon’ is already installed.
No update candidate for ‘power-profiles-daemon-0.30-1.1.x86_64’. The highest available version is already installed.
No hung applications…
Ouch, it is too complicated for a newbie on Linux… :-/
I’m just not that familiar with what works on a laptop. That Archwiki link has a lot of info.
It’s just a matter of getting the correct scaling driver and power profile. Someone with a laptop will come along and make it look easy.
Take the active line out of your kernel parameters that I had you change. I think you were on the right track with epp and powersave. It may have been balanced that was the problem but something was making your CPU run super fast.
Also, what desktop are you using?
KDE with Dev branch. But the problem was here long ago…
