(Get the code!)
Speaking to Lenovo won't automatically fix the issue, because it is way harder to get people to install bios updates than to accept kernel updates.
Fan control disengaged mode works: fan runs 4700 RPM, which keeps temperature down at 84 C after several minutes at full load. Unfortunately in disengaged mode the fan always runs 4700 RPM, no matter what temperature or load.
So, make the system switch between fan control modes according to temperature and its growth rate to narrowly avoid hitting 100 C (it needs to be done on many affected Lenovos).
