[SOLVED] Unusually high CPU temperatures on Hyprland

After spending one month managing to download Arch Linux manually (I had no prior computer science or Linux experience nor do I have much now), I downloaded Hyprland preconfigured HyDE. (almost) everything seems to work just fine, however, I'm reading strangely high CPU temperatures and sudden jumps (from 40°C to 90°C than back to 40°C in seconds), which tend to happen when I move quickly around windows and desktops. I tried downloading and enabling thermald and auto-cpufreq daemons, but none of them seemed to make any difference. I also tried running Hyprland on the dedicated GPU rather than on the integrated one, and it seemed to slightly mitigate the situation, but still made no big difference. I'm far from being an Arch Linux expert, but as a physicist I assume that there may be some mistakes in the temperature readings. Other than this temperature issue, programs seem to run decently smoothly. I haven't set up any fans program, but they get louder when temperature gets higher. I will post system info. I think it would be useful to also post htop readings, but to be honest I have no idea how to do that. Thanks in advance.
Note: My laptop is connected to an external monitor where Hyprland is running, while my laptop's monitor has the tty. Only using my laptop's monitor doesn't seem to make any difference.

Re: [SOLVED] Unusually high CPU temperatures on Hyprland

but as a physicist I assume that there may be some mistakes in the temperature readings

TDB is typically 100°C and the core temperature can change fast.

Check whether the CPU load moves accordingly.
If it's not some genuinely CPU intense hyprland feature, make sure you're not rendering in software on the CPU.
"glxinfo -B" for a broad oversight on that.

Re: [SOLVED] Unusually high CPU temperatures on Hyprland

Thanks for answering. I tried to run that program and Hyprland is running on the integrated GPU like it should. In the end I managed to solve the problem by installing a fan a power profile controller for msi a laptop together with auto-cpufreq. I turned fan speed up and eventually decided it was better to run Hyprland on the dedicated gpu anyway (I seldom use my laptop not plugged in). Everything's working fine now.
