Introduction

This page is a step by step guide to get fan control working on T2 Macs.

In some Macs, the fan has been found to work out of the box. In such a case the driver is not required until you want to force a certain speed or do some other configuration which can be done by the help of this driver.

Steps

  1. Install t2fanrd.

    • If you're using Arch based distros:

      1. Check if you installed Arch using our guide or added our repositories. If you haven't done that, follow this guide first.

      2. Install the package by running sudo pacman -S t2fanrd. (Do note that EndeavourOS Cassini Nova R1 already includes t2fand.)

    • If you're using Debian or Ubuntu based distros:

      1. If you don't have t2-ubuntu-repo, follow this first to add the repository.

      2. Install the package by running sudo apt install t2fanrd.

    • If you're using Fedora based distros (it should be installed by default, but you need to enable the service):

      1. Make sure our COPR repo is enabled: sudo dnf copr enable sharpenedblade/t2linux

      2. Install the package by running sudo dnf install t2fanrd

    • If you're using other distributions:

      You can compile the daemon by following the instructions given in this repository and add a systemd service.

  2. Enable daemon by running sudo systemctl enable --now t2fand.

  3. Edit the config and restart the daemon by running sudo systemctl restart t2fand if needed.

Configuration

The daemons config file can be found at /etc/t2fand.conf. You can change the activating temperature and/or fan curve to suit your needs. For more information, like how fan curves look like, check out the repository.
