Comment # 9 on bug 1172900 from S. B.

So, a few updates:

I did a fresh install of Tumbleweed, now using the Mate desktop. Needed
something more lightweight on this machine, and that alone has helped a lot
with the thermal problems and excess CPU load.

Then I had an ~2 hour Zoom meeting with ~25 participants using the stock
openSUSE 5.7.1 kernel, and then I had another similar Zoom meeting with the
Clear kernel. There are indeed major differences in CPU load, although they
don't seem to translate directly to a cooler system. However, I wonder if it's
because Clear has set different temp thresholds for the fan speeds, because the
fan seems to generally spin slower with the Clear kernel.
