Same problem. I use laptop PC, Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz, GPU GeForce GTX 1080 * 2. DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS". Linux kernel version is "Linux anomalydetect 4.15.0-66-generic".
I tried "cpupower" that controls CPU clock frequency. cf. https://wiki.archlinux.org/index.php/CPU_frequency_scaling # cpupower frequency-set -u clock_freq I tried the above with "clock_freq" set to "3GHz". (My CPU default max frequency is "4.5GHz") Then, "cpupower" was able to keep CPU temperature lowly without slowing down in my application!!

Opening youtube on firefox is enough for critical temperature shutdown. Using lm-sensors for monitoring on 18.04 the temp varies between 70 and 85°C with only firefox or chrome open and doing nothing. On my old 16.04 with same using, the temp varies between 55 and 70°C. First thought was the driver nouveau is the problem, and finally I was able to install by add "nouveau.modeset=0" at livecd boot options, without temp shutdown. After install I disable the nouveau at modprobe blacklist, but the system continues overheating and shutdown with basic usage. I have no idea what's happening with the bionic at my laptop. My laptop is a Samsung RF411 i5 2nd Generation and Geforce 540M.
