Chromium overheating CPU

Toshiba Satellite L775
Dual core Intel Core i3-2310M
Intel 2nd Generation Core Processor Family Integrated Graphics
Linux Mint 17.3 Rosa, Cinnamon 2.8.6
Kernel: 3.19.0-32-generic x86_64 (64 bit gcc: 4.8.2)

I use Firefox exclusively. However, the Citrix, GoToWebinar service does not work well in Firefox (launches, shares screen, no audio) Someone suggested using Chrome, and since I want to use "free and open source" software, I installed Chromium. I am finding it overheats my CPU

After several minutes, I begin to feel heat on the bottom of the laptop, then it spontaneously shuts down.

After reboot, I find the following lines in /var/log/syslog --

CPU2: Core temperature above threshold, cpu clock throttled (total events = 1)
CPU0: Core temperature above threshold, cpu clock throttled (total events = 1)
CPU1: Package temperature above threshold, cpu clock throttled (total events = 1)
CPU3: Package temperature above threshold, cpu clock throttled (total events = 1)
CPU0: Package temperature above threshold, cpu clock throttled (total events = 1)
CPU2: Package temperature above threshold, cpu clock throttled (total events = 1)
CPU0: Core temperature/speed normal
CPU2: Core temperature/speed normal

After several warnings, I find the following --

thermal thermal_zone0: critical temperature reached(84 C),shutting down

Has anyone experienced overheating when using Chromium? Any suggestions?

I have a work around -- launch Windows 7 in VirtualBox and use GoToWebinar in Firefox for Windows

Hi whiteEagle, sometimes Chromium runs a bit hard especially when its using one of its plugins - usually Flash. Try this to reduce resource usage:

Chromium:
Click (top-right button) Menu > Settings
Scroll down and click link Show advanced settings...
Privacy > Content Settings (click button)
Scroll down, select Plugins: Let me choose when to run plugin content
Click Done

Now plugins like Flash will ask for user input to activate, and can be limited to activating on only selected sites.

Chromium should now run cooler.

I'll give that a try, thx

I was watching the monitor, and CPU usage ran around 46-64 with occasional spikes to 100+

From the time stamps in syslog, I'm sure those spikes were the trigger for overheating.

I'll give your suggestion a try.

Disable hardware acceleration from Chromium.

Just a thought before you change settings. Is the internal cooling fan working? It should come on automatically when the CPU gets past a certain temperature so you don't have that problem. I have a Toshiba L770D, and when the CPU is working hard I can hear the fan come on, and feel the warm air blowing out the left side near the back. If the fan is working, but the computer is on a cloth surface, that can prevent the fan from drawing in cool air from the bottom.
