Every temperature sensor and fan in your Mac, with manual fan control and overheat protection.
Fans & Temperatures talks to the Mac's System Management Controller through ougi, a small open-source command-line tool built from source by Homebrew.
Install the tool — temperatures and fan speeds work right away:
brew install arturious/tap/ougi
To control the fans, install its root daemon once (changing fan speed requires root):
sudo ougi daemon install
The extension shows these commands, with a copy button, whenever a step is missing.
If fans are below max under manual control and any CPU or GPU sensor reaches 95 °C, the daemon returns the fans to macOS. Fans also return to automatic control whenever the daemon stops.
sudo ougi daemon uninstall
brew uninstall ougi
Show fan speeds and all temperature sensors, and control the fans
Switch all fans between automatic control and maximum speed
