I have MSI x470 gaming motherboard and AMD Ryzen 2600x and running Ubuntu 18.04.
The issue is, when I type
sensors in the terminal it gives me output on CPU temperature to be 90-108° C (only browsing the internet, a few tabs opened), but when I quickly reboot the PC and open the BIOS, it says CPU temperature is 37°-39° and the motherboard temperature is 37°.
I doubt that in less than a minute it can cool down from 100° to 39°. Unfortunately the motherboard reports only CPU and motherboard temperature, so no luck to check other sensors.
Can there be some sort of misreading in CPU temperature sensors while using the
sensors software command? Or can the CPU chip itself really be this hot under the cooler?
