I suspected you had an ATI card and you are using the radeon driver. I will show you a trick to get lower temps instantly.
Open terminal and write
- Code:
sudo su
echo low > /sys/class/drm/card0/device/power_profile
Check your temps again. You will hopefully see a significant drop, maybe 10 degrees down.
In order not to do this after every restart, we can make it permanent.
In terminal write:
- Code:
gksu gedit /etc/rc.local
In the file that will open, add the following line just one line above the word "exit 0" that is located at the bottom of the file.
(sleep 30 ; echo low > /sys/class/drm/card0/device/power_profile) &
That's it.
To test if we have made it permanent, reboot, and in terminal write
- Code:
cat /sys/class/drm/card0/device/power_profile
If the reply you get is "low", then all is well.
