Is anyone else experiencing very hot temps with minimal/no load under Fedora 36 while plugged in?
I noticed that when I’m plugged in the fans are almost always spinning and the ACPI sensor is reporting pretty high temps: 57C when idle, sometimes briefly jumping to 100C when loading a web page !!!. CPU cores are looking a little better, varying between 44C to 49C when idle and 55-65C when doing any sort of work. I already tried re-pasting with Kryonaut thermal paste twice but it makes no difference… The only way I can get the ACPI sensor to drop below 50C (hovering around 47C) is by running on battery with TLP set to max out at 60% CPU performance “CPU_MAX_PERF_ON_BAT=60”
Not sure about the program you are using here.
But it shows that two users are logged in. So maybe try to just log in a single user and see how the system behaves.
The “Load average: 0.60” means 60% load? Seems a lot to me for an idle system.
Which programs are you using to improve battery life?
E.g. TLP and auto-cpufreq are not playing nicely with each other.
Which Fedora performance profile are you using?
I just installed F36 on my 12th gen yesterday and my cpu is sitting at around 41°C while browsing / configuring the system, while having two external monitors connected and about 26°C ambient. No tlp, cpu-autofreq, powertop installed so far.
You can use powertop or powerstat to give you more information on what’s going on with your system at idle. I’d recommend using a LiveUSB distro (doesn’t really matter which, Ubuntu, Mint, Arch, etc) to see if you’re getting the same temps on other distros.
I don’t think your situation can be typical. In my testing, my 12th gen running Arch idles at about +3C over ambient.
