I installed 13.10 on my laptop and it seems as if the fan is constantly running. This is on a sony vaio ultrabook, the fan keeps running even if the cpu load is low. This problem does not occur when running windows, it will turn itself on/off when needed. I have searched posts on this forum for the same problem but none of the solutions worked for me.

Edit: Thank you, let me know if you need more information.

  • Hello and welcome! You will need to provide more information. Yesterday, another user asked the same question, but he also didn't provide enough info. Take a look at the post, see the comments, and add information editing your question. – Lucio Mar 24 '14 at 0:15
  • Please edit your question and tell us i) whether the machine actually hot and ii) what is the output of cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor. – terdon Mar 24 '14 at 3:13
  • Also, it would really help to know which solutions have already been exhausted. – mchid Jul 16 '14 at 2:35

Try installing lm-sensors and hddtemp

sudo apt-get install lm-sensors hddtemp libsensors4 xsensors

and then, run

sudo sensors-detect

Follow the instructions closely. You can safely accept all the defaults EXCEPT the final option. The final test may cause problems so you might want to skip the very last one. Reboot for the changes to take effect.

you can check temp by running

watch -n 1 -d sensors

Also, download the intel graphics installer from here
