Laptop fan speed shows 0 RPM and temperature reaches 80 degree but fan-like noise is clearly audible

  Fan Speeds (rpm): cpu: 0 fan-2: 0

So, first, the fans seem to be not properly detected even though I could hear a fan-like noise (which other components make those hissing noise), and it is loud enough.
Second, the battery runs out of power very quickly, as I recall it consistently drops from 100 to 0 in about one hour.
Third, the temperature readings are so high, which I think is accurate since the surface of the laptop is hot to the touch. At one point, the BIOS had to shut the system down on its own to prevent overheating.

I am not aware of any resource-hogging processes, the CPU load is constant at ~18%.
Why is my laptop temperature is high?

EDIT:
I found that one process is taking 99% of the CPU load. Here is the first few lines of the output of top:

I don’t think appimagelauncher is supposed to take up that much CPU load. Is it normal?

That is an AUR package, so you might want to see if the temperature issue persists after removing it.

Although I don’t use appimages on my system, I believe that the gearlever package in the extra repo is now the recommended one for managing appimages. Make sure that you install the repo version and not the package with the same name in the AUR.

If removing appimagelauncher doesn’t fix the temperature issue, then a more detailed look at your system may be required.

Please provide the output of:

inxi --filter --verbosity=8

or the short form (preferred):

inxi -zv8
Running `inxi` in `chroot`
Providing `inxi` when you cannot access your desktop environment

Thanks for your reply. Can you please tell me how important appimagelauncher is before I decide to replace it with an alternative? I check its package information and it was explicitly installed and was not a dependency of another package. So it looks to be safe to be removed but I just want to make sure which capability will be absent if it is not installed.

It is not important at all. If it was, it would be in the repos and not the AUR (which is not officially supported by Manjaro). So you can safely remove it without breaking anything.

Of course it is marked as explicitly installed, as is the case with any package that you manually install. Otherwise, with nothing depending on it, it would be removed every time you cleaned out your orphaned packages.

Thanks @scotty65! The temperatures drop to 60 degrees shortly after appimagelauncer is removed. But, what could have triggered that program to misbehave? I didn’t touch it recently and it never caused this CPU-hogging issue before.

The second sentence could explain the first.

AUR applications often need rebuilding after a system update, as the system packages/libraries they were originally built with on the device may have changed.

The more system dependencies an AUR package has, the greater the chance that it will malfunction or stop working after an update if it is not rebuilt by the user.

You may just have been lucky in that the issue didn’t happen sooner, as the appimagelauncher hasn’t been in the repos for quite some time (probably a year or more).
