I know that there are some threads to deal about this topic but neither has helped me. The problem is that the fan of the graphic-board permanently runs. I used ArchLinux on the same hardware without any problems but recently I changed to Ubuntu 16.04. Since then I have this problem with my noise fan!!

Here are some hardware informations :

**dmidecode**  noticed that ACPI is supported! My fan has a connector with four pins (pwa capable).  

**hddtemp** is installed.

  • Please edit your question to include the make and model number of your system, or if a PC the make and model of the motherboard. Also state which fan is making the noise: the CPU fan, the case fan or the graphics card fan. Check it is the correct fan by stopping it for a few seconds by touching its centre.

  • Hi Steve! I add the necessary information above. If I touch the fan it stopped and after releasing it starts again.

Change your graphics card driver from the Xorg driver nouveau to the proprietary Nvidea driver.

If this does not resolve your problem then follow the instructions to enable custom Nvidia graphics card thermal management NVidea fan speed tutorial
