You can use nbfc to control the fan

I'm using an Acer Aspire E5-573G laptop and nothing else worked to control the CPU fan, but nbfc. I'm using Ubuntu 18.04. The exact profile for my model is missing, but nbfc worked fine with another similar profile (Acer Aspire E5-575G). If you don't know which profile to use, you can try: mono nbfc.exe config -r

You will need the latest mono version to build it on Ubuntu 18.04, so don't forget to read How to build NBFC on ubuntu.

Also I edit the default profile to turn the fan policy more aggressive to low the temperature.

You can lower speed of CPU, it helps. Here is a script to auto lower speed of CPU when it reaches upper limit you choose. https://github.com/Sepero/temp-throttle/blob/master/temp_throttle.sh

You have switchable graphics. If you don't need the extra performance from the discrete AMD graphics card then you can switch it off permanently in the BIOS of your laptop.

If your BIOS has no option for that or you need the extra performance, then please look up this Q&A for solutions.

I find battery saving applications help a lot for overheating. laptop-mode-tools and tlp are both pretty good.

To install Laptop Mode Tools, run sudo apt-get install laptop-mode-tools From within Terminal.

To install TLP, run these commands in Terminal:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw
sudo tlp start

Hopefully, these will lower your temperature some. They brought mine down 10-20 degrees C, so any difference should be pretty noticable.

yeah it lowered the temperature but when I play some vedio on firefox or open multiple tabs ,the tempearture again increase and it reaches around 80-85, I have edited my question. — chitra, Jan 12 '14 at 18:49
