HOWTO : Cooler CPU under Ubuntu 16.04 LTS

The faster the speed of CPU, the more heat it generates. If your computer (desktop, laptop or server) encounters CPU overheating, you need to slow the CPU speed down in order to keep the CPU more cooler. The more cooler CPU, the better performance for some situations.

Step 1 :

sudo apt-get install linux-tools-common linux-tools-generic cpufrequtils thermald

Step 2 :

Insert the following line to "/etc/rc.local" and before "exit 0" :

sudo cpupower frequency-set -g powersave

Step 3 :

sudo sed -i 's/^GOVERNOR=.*/GOVERNOR="powersave"/' /etc/init.d/cpufrequtils

Step 4 :

Reboot your box

Remark :

To rollback, just replace "powersave" to "ondemand" or "performance".

That's all! See you.
