Fan working non-stop on Ubuntu 18.04 DELL 5480



Ubuntu 18.04 Bionic Beaver
Laptop: Dell 5480
CPU: Intel® Core™ i5


My solution steps (fans immediately shut off on last step):


Download .zip file (or git clone) to disable BIOS fan control for Dell laptops. 

https://github.com/TomFreudenberg/dell-bios-fan-control

Then, as root:

• cd Downloads
• unzip -t dell-bios-fan-control-master.zip (test zipfile; everything looked fine, so unzip files...)
• unzip dell-bios-fan-control-master.zip
• cd dell-bios-fan-control-master/
• more Makefile (look what it's going to do; looks fine, so compile with...)
• make

Compiled fine, so:
./dell-bios-fan-control 0 (turn off dell bios fan control)
BIOS CONTROL DISABLED


Fan was still idling around 2500rpm. Hmmm.. recalled post indicating uninstall then reinstall i8kutils with the same /etc/i8kutils.conf config file.


Uninstalled and reinstalled i8kutils with:

• apt-get remove i8kutils
• apt-get install i8kutils

Fan immediately stopped upon reinstalling i8kutils.


Looks like it's working. Fan turns on properly when cpu temp hits 55C then turns off quickly because fan came on at the high setting.


Will continue to monitor temperature and fan states with 'sensors' to ensure all is working as configured in /etc/i8kutils.conf
