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.
