Ventilator allways on high speed.

Asked by Rob Frerejean on 2012-11-05

Ventilator is running on high speed all the time. It never idle´s. How can I fix this? In Windows it was no problem. It did only run when hot.

Ubuntu 12.04 on HP Laptop G72.

Hi ,

open a terminal and try these commands

~$ sudo -i
~$ echo low > /sys/class/drm/card0/device/power_profile
~$ exit

wait 5-10 secs and see if temperature is down and ventilator slower.

If above works , you have to make it permanent with other commands. Above commands works only for one session.


or in a single command:

echo low | sudo tee /sys/class/drm/card0/device/power_profile > /dev/null

Much easier

If it works, we can add it to your startup

It´s still running fast. Air comming out is hot. I even changed the option in BIOS. Fan always on yes/no. Both options don´t work in my bennefit. Even updated the BIOS.

And that without any CPU drain. Just started Linux.
