Make sure your BIOS is up-to-date. The early i3/i5/i7 Lenovo (thinkpad, at least) BIOSes had significant issues with thermal management. Thermal management is done by the EC (Embedded Controller) part of the BIOS. Trip points, actions-to-take, etc... are all there. Make sure your BIOS is up-to-date.
If it was the BIOS, why does it not overheat with a different kernel version? BIOS bugs can be triggered by different kernel behavior
Well, I have updated the BIOS to the latest available version for my laptop and this didn't resolve the issue. Would have been strange if it did, but it would have been possible. As indicated before, if I use the same kernel but without the acpi_cpufreq kernel module the laptop behaves correctly and does NOT overheat. If I load the acpi_cpufreq module (and this one loads the mperf module) then the laptop overheats within seconds with full load.
