Not that I have noticed. Currently running 5.17.3-arch1-1. I don't usually push this machine too hard - maybe the most that I do is recompiling ffmpeg a few times a day, so it might just be a result of my usage patterns? I'll get back to you with more solid figures later tonight. EDIT: Just had a play around with sysbench running a few prime number tests while compiling a kernel or two. The k10temp-pci-00c3 (CPU temperature under lm_sensors) seems to stick around at a crispy +64.1°C for a good few minutes, before rising to +65.6°C. It seems to drop back down to +64.2°C. The fan is pretty noisy. The CPU drops down to +50.0°C within 60 seconds of the sysbench benchmark stopping, and the fan noise is completely gone after 90 seconds. Temp is +36.9°C. Idle temp looks like it's around +34.4°C. Not sure how I can measure the db level of the fans? I do have a recorder, so I might be able to do it that way. Not sure what a good way to actually benchmark the machine would be - it hasn't really come up as a necessity. Maybe I can use the Phoronix Test Suite? EDIT 2: Doing some searching, maybe I got the machine just in time? 5.17 looks like it added some code specifically around P-states for Linux. https://kernelnewbies.org/Linux_5.17#New_P-State_driver_for_modern_AMD_cpus https://kernelnewbies.org/Linux_5.17#New_P-State_driver_for_... ... Someone else with my exact same kernel version reports AMD issues being fixed in Arch that they previously had. https://www.reddit.com/r/archlinux/comments/u7kwza/recent_arch_update_5173arch11_solves_my_endless/ https://www.reddit.com/r/archlinux/comments/u7kwza/recent_ar...

Regarding the edit, that would make sense. I have the same laptop and first tried to run Ubuntu LTS, had some problems with the thermals, even though it was definitely usable. Tried Arch (with the 5.17 kernel, from Ubuntu LTS's 5.4 kernel) and the thermals were more or less identical to Windows, including the fan behavior. It's a really nice little machine! :D

If you compile in short bursts it's probably not going to affect you as much. With 4K screens and compiling a tiny bit of Rust, it starts being noticeable rather quick. I did notice that newer kernel versions do behave a bit better, but still require a bit of help to keep consistent performance plugged in.
