CPU temperature spike in 90c+ only when plugged in
My Asus Vivobook K571GT dual booting in Ubuntu 20.04 is recently started shutting down due to high temperature (reaching 99c+). These temperature are reached only when the laptop is plugged in.
The BIOS is updated to the latest, Ubuntu updated to the latest kernel. I've seen it might be due to nvidia driver not installed properly, so I tried a bunch of different nvidia drivers (460, 470 & 495). Tried disabling nvdia altogether running only with the integrated GPU. They all had the same results, when plugged in the temperature spike from a respectable 40c-45c to 95c in a second (without that much CPU load, i.e. running the apt update command will make the CPU temperature rise to 90c+), if I don't stop what I am doing or a command is running & I can't stop it in time the CPU will hit the 100c mark which trigger the shutdown. Interestingly if I unplugged while I get a high temperature warning the temperature goes back down to 45-50c in a second.
Has anyone experience something similar? The only thing I can think of for the rapid CPU temperature spike when plugged in but not on battery is the CPU getting "overclocked" when somehow. I'm not sure how I can verify this & if it somehow does how to prevent this from happening? An hardware issue like the AC adapter providing too much power?

Solution 1:
Your /etc/thermald/thermal-conf.xml is incorrect. It's two example files tacked together.
Try this somewhat generic .xml file shown below.
Note: You may end up customizing the following line...
<Temperature>60000</Temperature>
Then restart thermald with:
sudo systemctl restart thermald
