(UNRESOLVED) Fan always on/Increased fan speed

Hi Champs

i noticed that my fan always stays on irrespective of what activity i do, even when the system is idle, which therefore eats up the battery and gives me a backup of only 2 hours while as on windows i can easily draw close to 2.30 hours and sometimes even more.

I noticed there is an ongoing thread on this for ubuntu 12.04 here http://ubuntuforums.org/showthread.php?t=1976897&page=3.

This still seems to be unsolved . Can we pull out a fix/tweak for this one??

Here are the outputs for some commands i ran:

Code:

  cpufreq-info

  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 800 MHz and 2.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.

What i noticed is the post #24 on this thread http://ubuntuforums.org/showthread.php?t=1976897&page=3 does show a folder fan which shows up the speed and other info, but i dont have such a thing on mine..?

Thanks
Mark

Can you please give the result of

Code:

lspci -nnk | grep -iA3 VGA

Here it is

I have exactly the same GPU οn a Dell laptop, i3 processor, 4gb ram, and I am not facing any problem with temps.
Can you please post back the result of

Code:

You may have to press ctrl+c to stop it, but I want to see which program is causing your laptop eating up much ram and CPU and consequently increasing your temps.
You can also check that with system monitor

Code:

gnome-system-monitor

What is noticeable is that temp dont increase but just the fan always remains on. Unlike windows where it is fired only upon on demand.or whenever the processes are kicked up .

any bump on this guys??

Hi,

not doubting your intelligence but how are you using the notebook?, do you have it on a flat surface?, are you using it on the bed or couch?, have you checked to see if there is anything blocking the fan intake(s) like dust etc?.

Take a vacuum cleaner and set it to its lowest setting and hover gently over the fan intake(s) and see if that helps!!.

Take a look here, it might hold a clue for you:

I cannot give you any other advice!.

Regards Wolfman

at peace with this..thanks guys looks like ive goto live with this one.. Although to rule out any hardware, ive ordered a new CPU fan from the manufacturer....
