I have a Samsung laptop and installed Archlinux on it. At first everything was fine, I was even surprised at how nice everything was, no driver problems, everything went smooth. I could watch videos and it would barely get hot.
But after an update (with "pacman -Syu"), it started overheating (and getting slower as it starts to overheat). I'm not sure about what update was because I didn't notice it right away. I notice it the most when I'm watching videos but it is always hot and I can't really watch videos anymore because then it gets really slow.
I also installed flash, I'm not sure which one worked, I think it was "chromium-pepper-flash". But I also have "flashplugin" installed.
I don't think CPU frequency scaling utilities are the right solution because it was working before. What are my options? How do I detect what caused the problem?
Edit: Added some stats
Running chrome with 8 text/js tabs opened (Amazon, stackexchange, wired, ...): Average temperature: 75 Celsius degrees Average %CPU: 10% Average memory: 43%
Same as above but with a Youtube video in fullscreen: Average temperature: 93+ Celsius degrees (had to stop before it crashed) Average %CPU: 80% Average Memory: 47%
Does this mean the problem is with the GPU driver?
