Hello,
During charging on Manjaro KDE, the CPU temperature reaches ~77C.
The reason seems to be the CPU load that is higher than usual (normally it stays at the minimum 1.20 GHz in idle with the conservative
governor).
$ sudo cpupower frequency-info && cat /proc/cpuinfo | grep "MHz"
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.20 GHz - 4.46 GHz
available frequency steps: 3.20 GHz, 1.30 GHz, 1.20 GHz
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 1.20 GHz and 3.20 GHz.
The governor "conservative" may decide which speed to use
within this range.

, I see this command/process with high CPU usage:
irq/79-ACPI:Eve
What is this and why it’s using the CPU so much?
The temperature drops to ~60C when the battery reaches 90% charge and that process is gone when it’s fully charged.
Also, as a side question, why does cpupower
report 1.20 GHz frequency while /proc/cpuinfo
shows above 3 GHz?
