The temperature of my laptop increases very much while i am using ubuntu. i think because of the graphic card. can anyone tell how to lower the temperature. laptop gets discharged in less than 1.5 hrs.

Result of :sensors

coretemp-isa-0000

Adapter: ISA adapter

Physical id 0: +79.0°C (high= +87.0°C, crit = +105.0°C)

Core 0: +79.0°C (high = +87.0°C, crit =+105.0°C)

  • @Abdul-Rehman controlling fan speed wont solve the issue of heating, even the link you have provided with answer is not working for many peoples like in "/usr/sbin/pwmconfig" there are no pwm-capable sensor modules installed...and sensors results is completely showing the temperature is too high. – Sukupa91 Dec 01 '13 at 04:01

Most of times it could be about your graphic card gets warm and because your graphic card is integrated into your cpu the system thinks that cpu gets warm

install mesa-utils and mesa-utils-extras and reboot , for installing use the following command-

sudo apt-get install mesa-utils mesa-utils-extra

it will work for Intel Graphic Cards

If you are having NVIDIA graphic card then use bumblebee because mesa and NVIDIA will conflict with each other for sure.. to install bumblebee use-

sudo add-apt-repository ppa:bumblebee/testing

then for 12.04 and 13.04 use-

sudo apt-get install bumblebee bumblebee-nvidia virtualgl linux-headers-generic

otherwise for 13.10 use-

sudo apt-get install bumblebee bumblebee-nvidia primus linux-headers-generi

( for newcomes: the $ before this command is just an indicator that tells this command should be entered in a standard user command shell. if you want to use it just press <ctrl>+<alt>+<t> and copy-paste without this dollar mark )

If that doesnt work, try to

  1. Cleaning your laptop- As might be its because of just that, stopping fan from running properly.

  2. Update bios - After updating it can perform good operations like increasing compatibility .That solved my issue.

  3. Update Kernel

hope the very first suggestion will resolve your problem.

    use mesa.. as you don’t have NVIDIA , anyways these are just workarounds, there is no perfect answer of this. hope mesa will help you ,after that updating BIOS , and KERNEL is a good idea . – Sukupa91 Dec 01 '13 at 04:20

    nice answer and very good. – Raja G Dec 01 '13 at 04:28
  • @rajagenupula that happened to me once on dell n5010 , and this answer solved it right by after updating BIOS. – Sukupa91 Dec 01 '13 at 04:30
  • and how to disable a graphic card on every boot.is there any command? – rittik Dec 01 '13 at 05:00

Did you try nbfc

My laptop is an Acer Aspire E5-573G nothing else worked to control its CPU fan, but nbfc. I'm using Ubuntu 18.04. The exact profile for my model is missing, but nbfc worked fine with another similar profile (Acer Aspire E5-575G). If you don't know which profile to use, you can try: mono nbfc.exe config -r

  • It's generally frowned upon to spam the same answer to so many questions, even if the answer might be useful. – Merlijn Sebrechts Aug 14 '20 at 22:55
  • @MerlijnSebrechts, sorry. I understand. But I tried and search a lot before found this tool and it can help others users, too. – marciowb Aug 14 '20 at 23:04

Generally More heat means more processing , more work or more load on processor.we cant conclude always that due to only one device.

Actually more heat comes into the matter of processor and you can cool it by reducing the CPU frequency.

Look at this article : Linux Temperature & Ubuntu forums
