I have been running Ubuntu 14.04 on my HP Pavilion dv6 for 2 and half years now. For the most part, it runs perfect, however recently I have discovered CPU monitors and have realized that my CPU is idling at around 27%-40% and if I am using Firefox, downloading/uploading, or using multiple applications at once it skyrockets to 50%-99% (and this is no joke).

I know that this particular model is famous for overheating. I have had this thing since 2011, and ran windows 7 on it before switching over to Ubuntu. But I have never considered my CPU being the deal.

It has discrete dual graphics cards, as well as two processors.

I will give my specs below

What I am really curious about is whether I should be running the current proprietary drivers and what I should do to cool down my CPU for my particular model? Or, if it is a lost cause.

  • Also, the fan is always running. – RinIshi Jun 26 '16 at 22:02
  • Alright, so I ran the top command in terminal and I can see java taking up most of my CPU. I watched it jump from around 30%, up to around 50%, and shot up 103% before it dropped back down to around 48-50%. That is java specifically. I am super curious as to why it would run like it is. – RinIshi Jun 26 '16 at 23:51
  • Does it the CPU usage go down when you kill the Java process ? What do you see when you run ps -ww -fp <processid> in a terminal ? (You can see the process id in top or in the system monitor, and you can kill java from the system monitor too.) – JonasCz Jun 27 '16 at 11:33
  • Yes my CPU usage almost hits 8% when I kill the process. – RinIshi Jul 17 '16 at 0:35
  • I was not able to run that command in terminal. I recieved the message: – RinIshi Jul 17 '16 at 0:39

I ended up solving my CPU issue by removing Freenet from my system. Here is the forum I used to help me. https://ubuntuforums.org/showthread.php?t=792676
