acpi reports high temperature (60-70C) on idle (Ryzen 7 4800H)


I'm a bit concerned about this. I think that the temperature reported by acpi -t is way to high for the load, which is just some browser tabs, nothing else. I'm with Manjaro 20.0.2 and 5.6.15 kernel.

I'm regularly checking acpi -t and it usually outputs values between 60-70, sometimes higher. There are also outliers of 50-55, but I've never seen it below that. The temperature at home shouldn't be greater than 22. I don't really think 60C is reasonable under for such a load load and a fresh room temperature. I've also noticed that the temperature may vary in +/- 10C just within a second, so I'm not even sure about how reliable these numbers are. But still too high always.

I've tried to install sensors-lm but it just doesn't detect the sensors. In any case, this is the output of sensors:

tlp is up and running and the fans do work, I can hear them occasionally.

I also have to say that, when touching it, the feeling I have is that it's (quite much) cooler than another Lenovo I have that reports a constants temperature of 50-53 for each of its 6 cores. But these numbers are pissing me off, to be honest.

I don't have a zen cpu but a quick search on aur showed a zen specific monitor and kernel module:

I can't say if this will work for you but it's at least worth reading and may point you in the right direction. Sorry I couldn't help further. Good luck.

Or try linux-5.7.0, which has additional AMD support. Manjaro supports multiple kernels from the advanced grub menu. Normally I wouldn't recommend an early release of a new kernel series, but when the hardware is so new, it merits an exception. The hardware is new enough that you might need to wait for 5.8 or even 5.9 for better native temperature sensing. Keep reading the forums (not just here). Often, workarounds will be posted as users discover them (kernel arguments, .conf edits, ...)

Will have a look later, you already helped a lot, thank you!

I didn't know that the 5.7 was finally released; I've been checking it regularly but refrained to install the rc, as the last time I was messing with the kernel I broke the thing. Then I'll also check if the patch for the brightness control was already introduced. I'll make sure that I have a timeshift backup before upgrading. Thank you!

Let us know how you get on.

Btw, how can I install the 5.7 kernel? I've already run sudo pacman-mirrors -f && sudo pacman -Syy but the latest kernel I can see in both the GUI and pacman with pacman -Ss linux57 is still the rc7 version.

What is the temp reported in your BIOS? Also note that BIOS temps are usually higher than in the OS due to power saving features in the kernel.

If your BIOS is also abnormally high, it could be that the CPU is not correctly configured.

I lived with a 2700X running at 60c for over a year before I realized that I needed to run an ASUS configuration utility built into the BIOS. Now it runs at about 40c (I live in a hot climate).

From a fresh boot, it was marking 30-35C and the fans running at ~2300rpm. I've made a little stress test with a ML project that made acpi report 90C, then immediately reboot into the BIOS (5-10s since the script finished) and the temperature was 40C with the fans still running at 3500rpm. So I guess that acpi is basically wrong. That was a great idea for testing, thanks. And as said in the OP, never with the feeling of actual hotness in the laptop.

I still need to test the utility posted above, will update with results.

Sounds like the sensors need to be offset. A similar thing happened when the 2XXX series was released. All reported temps were 20c hotter than actual. It took a few months for those fixes to make it into the kernel.


You can use Manjaro Settings Manager or the KDE Settings Manager. Be sure to reboot and select it after post.

Yeah that's what I meant with that I wasn't seeing it in the GUI. The latest one I'm seeing is the 5.7rc7, experimental.

Ah, sorry, it's still in testing.

[Testing Update] 2020-06-03, to find out more. linux57 5.7.0 is supported.

If you want to try changing to the testing branch follow the steps here
Manjaro Wiki - Switching Branches

Alternatively, it shouldn't be too long before it's all released in stable. released 5.7.0 on Sunday (5/31). It takes time to be checked by the Manjaro devs and the Manjaro testing community before it is pushed to the stable branch. I have seen some 5.7-rc wifi issues reported in other threads, so it might take a few 5.7 maintenance releases before that is all worked out. In any case, it looks like the kernel is reporting temperatures that are too high for these new AMD processors.

Tried it, and it's just showing the core frequencies. I've opened an issue. I'll keep this thread updated.

I had trouble with my temps, because the cooling-paste was very poor from the manufacturer. It was horrible and after cleaning and replacing it my average temps went down from 70°C to 45°C. The build-quality of a lot laptops is very often poor.
