My laptop was making noises under load, and sadly trayfreq was unable to set cpu frequency for some reason.

Oh, that is a very good idea for me to try tomorrow when I do my next build -- that is when it gets really hot. I do not care if it is slower but at least then I can work on other things while doing a build. THANKS. On Fri, Mar 1, 2024 at 5:16 PM Andrew Randrianasulu <[email protected]> wrote:

this sets max frequency to 800 mhz instead of 2.5/3.0 ghz as usual.
note that 25 is percentage, and on different core iXXX processors results can be different.

The cpupower utility can be used to set minimum and maximum cpu frequencies and frequency scaling governor. I use it on my intel and amd laptops. With some governor you can't set frequencies, try to change them. I hope this helps. Best regards, Andrey сб, 2 мар. 2024 г., 03:16 Andrew Randrianasulu via Cin < [email protected]>:

Thank you Andrew and Andrey.

Yes, this helped - laptop was cooler when I used the "powersave" governor and it was OK that the build took longer since I wanted to do other things at the same time.
echo 25 > /sys/devices/system/cpu/intel_pstate/max_perf_pct
this sets max frequency to 800 mhz instead of 2.5/3.0 ghz as usual.

Yes, this motivated me to find a solution. I had to use cpupower utility
because it was an AMD laptop instead of intel.
