NZXT CLI

A simple NZXT tool for managing fans and LEDs.

Install

To build the tool from source code, You need:

• Rust: Version specified in Cargo.toml or greater.
• libudev and libcap

cargo install --path . --locked

After that you need to install udev rules:

# Copy rules file
sudo cp ./contrib/60-nzxtcli.rules /usr/lib/udev/rules.d/60-nzxtcli.rules
# Reload rules
sudo udevadm control --reload-rules && sudo udevadm trigger

How to use

List all devices:

  }

Set the same color for all LEDs on all devices:

nzxtcli set-color ffaabb

Sync LEDs color to the CPU temp (or any other temperatur sensor). Use sensors to find preferred temperature source, then run

for i in /sys/class/hwmon/hwmon*/temp*_input; do
  echo "$(<$(dirname $i)/name): $(cat ${i%_*}_label 2>/dev/null || echo $(basename ${i%_*})) $(readlink -f $i)";
done

to find path to desired file.

Then run this tool:

nzxtcli cpu-temp \
    /sys/devices/pci0000:00/0000:00:18.3/hwmon/hwmon4/temp1_input \
    --interval 100ms \
    --base 20 \
    --warn 90

You can create a systemd service for this command, see the example.
