I have Dell Inspiron 5520 laptop. Its fan is always in running state.


  • OS Ubuntu 12.10 x64
  • CPU Intel Core I5 3rd gen
  • Video Radeon 7670M.

I have checked the system monitor to check cpu , then i found that one cpu uses is always 100%. enter image description here What do I need to do to stop the noise from my laptop?

dual/hybird graphics card? – Web-E Feb 22 '13 at 14:36

Is the FAN running only under Ubuntu or with other OS too? Maybe the notebook need to be opened and cleaned...?!

Maybe its possilbe to set the temperature when the FAN should start to run to a higer value in the BIOS. This can be dangerus, when the FAN doesen't start early enough and the notebook gets too hot.
