Hi! I'm still facing this issue with 0.21-1, but not 100% sure (might be an issue in intel_pstate as well).
In short: on 0.21-1, facing an issue, no_turbo is 0, turbo_pct - file does not exist; writing 0 to no_turbo (even though it was 0 already) fixes the issue. More details: * Ubuntu 23.10 * power-profiles-daemon/mantic,now 0.21-1~mantic1 amd64 [installed,automatic] * Intel i7-14700HX (base 2.1Hhz, Turbo Boost up to 5.5Ghz + efficiency cores with a bit lower freqs) * NO cpufreqd and auto-cpufreq * thermald installed and running $ grep . /sys/devices/system/cpu/intel_pstate/* /sys/devices/system/cpu/intel_pstate/hwp_dynamic_boost:0 /sys/devices/system/cpu/intel_pstate/max_perf_pct:100 /sys/devices/system/cpu/intel_pstate/min_perf_pct:16 /sys/devices/system/cpu/intel_pstate/no_turbo:0 /sys/devices/system/cpu/intel_pstate/status:active Note: turbo_pct - file does not exist Further observations: * Right after booting, even though temp is ~45-50C, I see the "high hardware temperature" in system settings. * cat /sys/devices/system/cpu/intel_pstate/no_turbo returns 0 * Running prime95 saturates all cores at their max non-boost frequencies (2.1Ghz for P-cores and 1.5Ghz for E-cores), temp remains at ~65-70C Here's the most interesting/puzzling part: even though no_turbo was already 0, explicitly writing 0 to it (echo 0 | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo) fixes the problem: * "high temp" warning in settings immediately goes away * prime95 on single core: cpu clocks go up to 5.1Ghz, ~90C temp on that core + ~50C on others * prime95 on all cores: clocks up to ~3.5Ghz, then gradually go down to 2.5-2.8Ghz (80-85C all cores) Obvious workaround is to just write 0 to no_turbo after boot... but this feels quite strange :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942616 Title: Settings Power says high hardware temperature To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/power-profiles-daemon/+bug/1942616/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
