If the heat problem still persists then next please run 'top' to confirm
which process is using the most CPU.

Also, please run this again:

  journalctl -b0 > journal.txt

  Lenovo X1 Extreme with thunderbolt docking station causes overheat
  with concert of fans

Status in xorg-server package in Ubuntu:

Bug description:
  Hey everyone,
  after resolving some of the problems I got after upgrading to 20.04 [1] I'm 
now using my Lenovo X1 Extreme Gen 2 with the thunderbolt docking station (and 
an HDMI monitor attached).
  Everything worked out of the box, except for the increased general heat of 
the system (constantly over 70 °C) and the consequent concert of fans that 
makes working aside the (closed) laptop almost impossible.
  It is really hard to understand if there's a specific process causing the CPU 
to be so constantly stressed, and what is more curious is that monitoring the 
general status of the system resources (CPU, Memory and so on) there are no 
peaks, it shows a normal usage, which is what I do: browser, mail, and some 
console. Something I would expect that with 16 cpu and 32 gigs of RAM should 
not be a concern.

  Both thermald and tlp services are obviously installed and running.
