Ubuntu 22.04 - CPU constantly running too hot at 90°C

cy flag

the output of sensors is constantly looking something like this with regular spikes over 90°C or 95°C for multiple seconds. This does not seem healthy for the life of the CPU.

I am using a ThinkBook 16 G4+ IAP with an i7-12700H

Is there a way I can tell my system that I would prefer a temperature under 85 even when that means throttling?

sensors output:

Core 31:       +59.0°C  (high = +100.0°C, crit = +100.0°C)

I also saw some cores seem to have a higher max. freq. and wondered if that might have something to do with it

Your 12th generation Intel processor will have both performance cores and efficient cores, with the performance cores able to go to higher frequencies. And yes, the temperature (and power) verses frequency curve can be rather steep at the highest frequencies. You might be running some thermal throttling daemon already and merely need to reduce the trip point temperature. See [here](https://askubuntu.com/questions/1373633/how-to-troubleshoot-cpu-hw-crash-in-ubuntu-18-04/1373784#1373784) for an old answer about this. Your processor should be able to do TCC Offset thermal throttling.

Bios update? The release note say something about "... thermal ...".

I checked on Windows and the BIOS is already the newest version sadly. @Marco

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
