This is an enhanced version of Allan McRae mbpfan
mbpfan is a daemon that uses input from coretemp module and sets the fan speed using the applesmc module. This enhanced version assumes any number of processors and fans (max. 10).
- It only uses the temperatures from the processors as input.
- It requires coretemp and applesmc kernel modules to be loaded.
- It requires root use
- It daemonizes or stays in foreground
- Verbose mode for both syslog and stdout
- Users can configure it using the file /etc/mbpfan.conf
Supported GNU/Linux Distributions
We provide scripts to to load mbpfan daemon at system boot for many distros. Please note that the support is provided by volunteers. mbpfan needs tests and bug reports.

Be sure to load the kernel modules applesmc and coretemp.
These modules are often automatically loaded when booting up GNU/Linux on a Macbook. If that is not the case, you should make sure to load them at system startup. This is usually achieved by inserting the following two lines in the file
Please check the relevant documentation of your GNU/Linux distribution.
See mbpfan-git at AUR. Otherwise, please refer to the Generic Instructions.
Then, refer to the Generic Install Instructions.
Otherwise, a step-by-step tutorial for beginners is available on my website.
Type the following command to add the overlay
sudo layman -a andjscott
Then install it
sudo emerge -av mbpfan
Generic Install Instructions
sudo make install
It copies mbpfan to /usr/sbin, mbpfan.conf to /etc, README.md to /usr/share/doc/mbpfan, and mbpfan.8.gz to /usr/share/man/man8
Run The Tests (Recommended)
It is recommended to run the tests after installing the program. Please run the following command from within the source directory.
sudo ./bin/mbpfan -t
sudo make tests
If not installed, run with
If installed, manually run with
If installed and using the init file, run with (Ubuntu example)
sudo service mbpfan start
Starting at boot
For systemd based init systems (Ubuntu 16.04+), the file mbpfan.service has been provided. For using it, execute:
sudo cp mbpfan.service /etc/systemd/system/ sudo systemctl enable mbpfan.service
For upstart based init systems (Ubuntu before 16.04), an example upstart job has been provided. For using it, execute:
sudo cp mbpfan.upstart /etc/init/mbpfan.conf sudo start mbpfan
Debian An init file suitable for /lib/lsb/init-functions (Debian) is located in the main folder of the source files, called mbpfan.init.debian Rename it to mbpfan, give it execution permissions (chmod +x mbpfan) and move it to /etc/init.d Then, add it to the default runlevels with (as root):
sudo update-rc.d mbpfan defaults
Redhat, CentOS, Fedora An init file suitable for /etc/rc.d/init.d/functions (RHEL/CentOS & Fedora) is also located at the same place, this file is called mbpfan.init.redhat. Also rename it to mbpfan, give it execution permissions and move it to /etc/init.d To add the script to the default runlevels, run the following as root:
chkconfig --level 2345 mbpfan on && chkconfig --level 016 mbpfan off
To automatically run mbpfan at boot, run as root:
rc-update add mbpfan default
systemd As a special bonus, a service file for systemd is also included. To use it, execute the following (as root):
sudo cp mbpfan.service /etc/systemd/system/ sudo systemctl enable mbpfan.service sudo systemctl daemon-reload sudo systemctl start mbpfan.service
To start the service automatically at boot, also execute the following:
sudo systemctl enable mbpfan.service
Usage: ./mbpfan OPTION(S) -h Show the help screen -f Run in foreground -t Run the tests -v Be (a lot) verbose
