I am having the issue that whenever I turn on Ubuntu (I'm using dual-boot with Windows 10), fans in my notebook will always run at full speed even when I'm not doing anything. The same thing happens on every Linux distro I had, but on Windows it's not doing so.

My notebook: Acer E5-575G-5328

I tried those common resolutions as to change the GRUB setting to make it equal to acpi_osi=!Windows 2012, but it didn't work. I am really getting annoyed by listening to the fans always spinning.

Please, can somebody give me a working resolution to this issue?

Thank you

EDIT: This is the output of lspci -k | grep -EA3 'VGA|3D|Display'

  • Please edit your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command.

Try also the following:

try looking at the output for firmware interrupts:

grep . -r /sys/firmware/acpi/interrupts

You'll get a whole block of different outputs, for example:

/sys/firmware/acpi/interrupts/gpe01:19241984   enabled

Should you encounter any one of these, with a large number following gpexy: and it being enabled, try disabling it in crontab:

sudo crontab -e

i suggest you use nano for editing. Then add it:

@reboot echo "disable" > /sys/firmware/acpi/interrupts/gpe01 

with gpe01 being replaced with interrupts according to your previous output.

Reboot and see if it worked.

  • Thank you for your response, I do not have such high values in my output, the maximum is 72, disabled and then there is 63, enabled. So, the values are low.

Your Nvidia adapter is always in use. Run

sudo prime-select intel

Then log of and log on.

The fan should stop.

  • Thank you for suggestion, but it didn't work. I tried to apply this command, logged out, powered off my notebook, restarted it, but still the fans are running at full speed.
