Ok, let me check. That sounds like something that could make machine
hotter.

My problem seems to be that machine seems to run way hotter with 6.10,
and when it hovers around the 97C limit, it is unusable with all the
throttling.

It gets unusable with 6.9 at 97C, too, it is just that it is harder to
make it so hot with 6.9.

(And yes, I'm running Chromium, and yes, that means websites influence
this. Media playback also does, 1080p video pushes thermals close to
the limits even on good kernels.)

Thanks and best regards,
								Pavel
