Ubuntu is overheating at my laptop. 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.
