Overheating with Adobe Flash running in Firefox 24.6.0

[Fufu]

In Firefox 24.6.0, one tab only loading 1 flash video the CPU F degrees jumps original temp +20F, then slowly climbs to ++60F. I am only running one instance of Firefox and Flash Player on my laptop. The PC slows down, due to, overheating. My laptop is on a hard surface and no other programs running. After the laptop reaches tempatures over +200F total. I shut down the laptop. I have powersave mode on, yet Firefox playing adobe flash bucks the limits in CentOS 7.0.4.2.

Maybe try bias 15? I'm not sure. Does it happen only when viewing a particular website? Does flash in chrome do the same thing? What does cpu utilization and the load averages look like?

Code: Select all

cpupower set --perf-bias 15;

I haven't tried this yet, but it seems that my laptop runs a little hot even under low loads. Sort of looks like Intel speed step is not being used and the processor is on high at all times. May or may not be related to the above problem.

Running on battery is good though, so part of the system might be working, I don't think I have the CPU running lower on battery in my bios (need to check).

The CPU temperature jumps when Adobe Flash plug-in is being used on any website.

I disassembled my laptop to reapply the factory thermal compound with Arctic Silver 5.

Arctic Silver 5 thermal compound did not solve the CPU temperature spike, but it did lower the overall CPU temperatures by 55F / 13C.

I have not tested this yet @nbritton. I will report back when I do.
