This is not too surprising. It's still a bit of a mystery what's different
between machines that behave fine and those that don't.

I have the same machine, and it's never been problematic.

I note I'm at the same old bios I had when I first purchased it.
bios0: vendor LENOVO version "N23ET61W (1.36 )" date 01/17/2019

And there are some other bios options, regarding bios/efi and thunderbolt and
suspend that can be set one way or the other. I have everything turned down to
whatever the "oldest" settings are. CMS boot, etc.

If you run top -S, do you see any process taking lots of CPU?

inteldrm changes cause high temperature / fan speeds (was: Downgrade 6.6 to 6.5)

Hi,

Sorry if someone gets this twice. My first version didn't go to the list.

I have same problem on my Dell Optiplex 990 (running in "headless" mode,
no monitor attached!).

After upgrade from 6.5-stable to 6.6-current, CPU temperature
increased from 50C to 70C..80C and the fans are running at full speed.

So, I went and cloned OpenBSD src tree from https://github.com/openbsd/src/

Then I started bisecting kernel commits from 6.5-release to 6.6-current:
 > ls -1 kernels
bsd.apr10.a72c25aac8e43fe
bsd.apr14.505701c75b30a46033a8
bsd.apr23.53d03815630664

bsd.may1.4a0e86bfb04cce9
bsd.may19.01b2b04ad452620a32

(Note the list isn't complete. I noticed that kernel became backwards
incompatible at some point in April and I had to create a temporary
6.5 installation on another disk.)

Eventually I pinned the problem down to April 14/15:

FAULTY 091f8f6587f dlg  Mon Apr 15 02:59:41 2019 +  the myx_cmd
FAULTY 1bbcb699ab8 dlg  Mon Apr 15 00:28:29 2019 +  there's a bunch
PROBLEM! 7f4dd37977d jsg  Sun Apr 14 10:14:50 2019 +  Update shared 
drm code
OK 505701c75b3 visa Sun Apr 14 08:51:31 2019 +  Add lock

I must admit that I don't have yet any idea how to fix
the problematic commit (or what is actually wrong there).

Reverting 7f4dd37977d didn't work for latest 6.6-current as there
have been too many changes after that.

I also tried to check the latest changes from linux-4.19.y,
but didn't spot anything useful.

Yours,
  Tero
