If you're using KDE Plasma 5 and some programs make CPU temperature high, (80~90℃) try turning off "Enable taskbar notification" in Applications - Launch Feedback.
I had this problem with Okular. Whenever I opened Okular, Okular icon on taskbar "rotates" quite a long time and plasmashell suddenly eats 30% of CPU. As I wrote, turning off "Enable taskbar notification" solved it. It lowered temp about 20℃ surprisingly.
It is obviously a bug which should be fixed, but at least this workaround may help some people. :^)

thanks. In my case it was devouring the battery of my laptop, the cpu fan was running all the time...
