Corsair do not currently provide software for the Corsair Commander Pro on Linux. This post details how I achieve nearly all of the functionality provided by Corsair Link using a Linux based CLI.
These features are now part of the Debian 11 repository, making the whole process much simpler.
Install LiquidCtl
Liquidctl is a cross-platform tool and drivers for liquid coolers and other devices (Corsair Commander-Pro & certain Corsair PSUs).
apt install liquidctlLiquidCtl is now installed, we can use the following commands to initialize it and monitor the temperature sensors and fan speeds:
liquidctl initialize all
liquidctl statusHere is the sample output from the status command on my server:

liquidctl --match "Commander Pro" set fan1 speed 100Installing Sensors
In addition to monitoring your Corsair Commander Pro, you will probably also want to monitor the CPU & GPU temperatures. This can be easily achieved by installing Sensors:
apt install lm-sensorsYou can now get a command line output of motherboard & GPU based sensors by using the simple command sensors:
sensorsHere is a sample output from sensors:

Glances is a cross-platform curses-based monitoring tool which aims to present a maximum of information in a minimum of space, ideally to fit in a classical 80×24 terminal or higher to have additional information. It can adapt dynamically the displayed information depending on the terminal size. It can also work in client/server mode. Remote monitoring could be done via terminal or web interface.
To install Glances you need to have a python development environment, which can be install using the following command-
apt install python3 python3-dev python3-jinja2 python3-psutil python3-setuptools hddtemp python3-pip lm-sensors -yGlances can now be installed-
pip3 install glancesYou can now run glances. Sadly, Glances my does not display the output from LiquidCtl.
glancesAs glances is a captive process, you will need to exit when done by typing “Q”. Alternatively, leave it permanently running in a separate terminal process!
Job done.
