Overheating (fan problem) in ubuntu 18.04.2. What should I do?

Question

I have an ASUS S510UA which came with Windows 10. I replace the HDD with an SSD and added another 8 GB ram memory.

I installed Ubuntu 18.04.2 in parallel and the fan is not working well.

When I am using Windows it never gets hot. However, when I am on Linux, it always gets hot.

I have already installed lm-sensors. When I run sudo sensors-detect, this block at the end of this message is what I get.

I tried this: Slow Fan Speed in Ubuntu But it didn't solve the problem. It just turns on the fan when ubuntu is starting, but the computer still gets hot.

Then I tried installing ACPI, because it was mentioned in another post that I could not find again: sudo gedit acpi-call-dkms But it didn't solve it either.

Is there anything else I could try?

Thanks in advance!

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver 'coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Answer 1

Part of the answer lies in how you handled the recommended modification to your modules, suggested by sudo sensors-detect. That program is asking you to install the coretemp module, and it defaults to "No". The second half is in using the Sensors output to run the Fancontrol module.

1st, lets add the module to your system

sudo cp /etc/modules /etc/modules.bak
sudo nano /etc/modules

Scroll to the bottom, add the line coretemp if it is not there, and press Ctrl+o to output the file and Ctrl+x to exit the editor

Now you need to install the program fancontrol, configure the pwm fan control units, and ties them into the sensor package:

sudo apt install fancontrol
sudo pwmconfig

pwmconfig will walk through the process of testing the fan for it's ability to control the fans, and allow you to set custom levels of temperature for turning the fans on and off. Then you need to set the output of sensors for Fancontrol.

sudo sensors -s

Finally, enable and start the Fancontrol service

sudo systemctl enable fancontrol
sudo systemctl start fancontrol

Finally, you can monitor both the temperature sensors and the fan speed at the terminal with sensors command. To continuously you can watch sensors, and for more advanced temperature monitoring you could use a program such as psensor

Answer 2

I got the same error while trying to run sudo pwmconfig. I found that the main cause of the problem was over-clocking of the CPU. Disabling turbo boost from BIOS will reduce the problem to some extent. But the CPU frequency will still be at maximum. There is a temporary work around for this by manually changing the CPU frequency governor.

Disable ondemand for CPU governor.

sudo systemctl disable ondemand

Install linux kernel tools and change the frequency governor to powersave.

sudo apt-get install -y linux-tools-$(uname -r)
sudo cpupower frequency-set --governor powersave

This should resolve your issues until there is an official update to handle this. You can find a more detailed explanation of the solution here: Ubuntu 18.04 Overheating Problem.

Answer 3

I would recommend installing thermald (it's meant for Intel CPUs) to solve this. It uses fan control, CPU's power states and idle commands to control temperature, so should be more efficient than just fan control. And remove other conflicting solutions. 'on demand' CPU governor should be fine.

And sure you need coretemp module loaded for it to work. Without sensors readings it's useless.
