I have an Acer 4830TG notebook, with freshly installed Ubuntu 18.04. All seems to be fine, but it gets overheated.

I have the following output of nvidia-smi:

I also have tlp installed. I tried to purge and re-install the driver, but it did not help. With X.org X server it is also overheating.

So I would be very grateful for any suggestions that could help solve the problem.

Which OS were you running prior to Ubuntu? Were there any temp problems with that OS? Here is a link to install Psensor which will allow you view the temps in an applet at the top of the screen.

Install Psensor

Usually these problems are caused by blockages in the ducting of the machines air passages. Do you have a dog or cat that sheds? Is the machine fairly dusty. 9 times out of 10 cleaning the fan and air intake ports with compressed air will solve these problems as will disassembling the bottom of the laptop and then manually cleaning the debris out. Could you please try that and report back with the results.

  • I had 14.04 before, it was fine. I have sensors installed, and the temperature seems to be really high coretemp-isa-0000 Adapter: ISA adapter Package id 0: +90.0°C (high = +86.0°C, crit = +100.0°C) Core 0: +88.0°C (high = +86.0°C, crit = +100.0°C) Core 1: +90.0°C (high = +86.0°C, crit = +100.0°C)

  • Deleted my comment, just realized those are in Celsius, not farenheit. Can you post the output of the "top" command so I can which processes are running? Also, do you hear the fan audibly running? Were you able to remove the bottom and clean it out (even if your confident that its clean, just take a quick look).

  • Yeah, but the notebook is really hot, and playing online videos in full screen makes it really slow

  • Its slowing down so it doesnt die completely. At those temps though, it wont be long. Take a look at my previous comment and let me know what you find.
