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.
How do I know if applesmc and coretemp are loaded?
In most distributions, you can run the following command:
lsmod | grep -e applesmc -e coretemp
If you see
applesmc listed, you are all set.
If you do not see
applesmc listed, you must load them.
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.
mbpfan package with:
sudo emerge -av app-laptop/mbpfan
Generic Install Instructions (All Other Operating Systems)
sudo make install
It copies mbpfan to /usr/sbin, mbpfan.conf to /etc (and overwrites existing files), README.md to /usr/share/doc/mbpfan, and mbpfan.8.gz to /usr/share/man/man8
Run the tests now, see two sections below.
If you would like to compile with Clang instead of GCC, simply set your system's default compiler to be Clang. Tested with Clang 3.8 and 3.9. Tested with Clang 4.0 along with llvm-lld (The LLVM Linker).
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+), see the systemd section below.
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
Usage: ./mbpfan OPTION(S) -h Show the help screen -f Run in foreground -t Run the tests -v Be (a lot) verbose
