This is an enhanced version of Allan McRae mbpfan

Fan-Control-Daemon 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.

Supported distributions:

  • Ubuntu
  • Debian
  • Archlinux
  • Fedora
  • RedHat
  • CentOS
  • Gentoo

This section reports the iMac models where mbpfan was tested successfully.

  • iMac5,1 17" (Intel T7400 (Core 2 Duo) - Linux 14.04 Ubuntu)


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 /etc/modules


Please check the relevant documentation of your GNU/Linux distribution.

Arch Linux

See mbpfan-git at AUR. Otherwise, please refer to the Generic Instructions.


Install the build-essential package. Then, refer to the Generic Install Instructions.

Otherwise, a step-by-step tutorial for beginners is available on my website.

Generic Install Instructions

Compile with


Install with

sudo make install

It copies mbpfan to /usr/sbin and mbpfan.conf to /etc

Run The Tests (Recommended)

It is recommended to run the tests after installing the program

sudo ./bin/mbpfan -t


sudo make tests

Run Instructions

If not installed, run with

sudo bin/mbpfan

If installed, manually run with

sudo mbpfan

If installed and using the init file, run with (Ubuntu example)

sudo service mbpfan start

Starting at boot

Ubuntu For upstart based init systems (Ubuntu), an example upstart job has been provided for use in place of the LSB-style init script. To use, 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

Gentoo An init file is available for gentoo users: mbpfan.init.gentoo To install, run as root:

chmod +x mbpfan.init.gentoo
cp mbpfan.init.gentoo /etc/init.d/mbpfan

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 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
