Better fan control for HP ProBook 430 G2.
On my HP ProBook 430 G2 laptop running Debian or Arch Linux, the fan is much too zealous to my taste, running quite fast even when there's nearly no load on the system. These scripts take control of the fan and apply a more moderate policy. On my laptop this works better than the original fan control software, meaning that the fan runs much less, but your mileage may vary. And of course, it's nobody's fault if you wreck your hardware!
The core scripts probook_ec and fanslow are taken from
https://github.com/k3mpaxl/fanspeed with no or only minimal modifications.
Further information on the original scripts can be found at

The probook_ec script is used to change several hardware settings of a
laptop. Useful things you can do with it include switching the fan off and
resetting the embedded controller (I guess that means something like returning
control of the fan to the firmware):
# probook_ec FANOFF
# probook_ec FANRST
The fanslow script monitors the temperature and sets the fan speed as
needed.
The fanslow.service file is a systemd service unit file used for
autostarting and running the fanslow script as a background daemon.
On Arch Linux, you can install from the AUR: https://aur.archlinux.org/packages/fanslow-probook430g2/
On other distributions, use the Makefile for installation and removal. If you
are picky about your installation paths (like /usr/ vs. /usr/local/) you
should probably adapt the Makefile as well as the fanslow and
fanslow.service files prior to installation.
# make install
# systemctl enable fanslow
# systemctl start fanslow
# systemctl stop fanslow
# systemctl disable fanslow
# make uninstall
You can watch the script working with the usual systemd tools:
# systemctl status fanslow
# journalctl -u fanslow
