# liquidctl
> Control liquid coolers.
> More information: <https://github.com/liquidctl/liquidctl>.
- List available devices:
`liquidctl list`
- Initialize all supported devices:
`sudo liquidctl initialize all`
- Print the status of available liquid coolers:
`liquidctl status`
- Match a string in product name to pick a device and set its speed to a flat 50%:
`liquidctl {{[-m|--match]}} {{string}} set {{fan|pump|...}} speed 50`
- Set a gradual fan speed curve that is 0% at 20°C, 50% at 50°C, and 100% at 70°C:
`liquidctl set {{fan|pump|...}} speed 20 0 50 50 70 100`
- Set the liquid cooler RGB lights (supported modes depend on the model):
`liquidctl set {{fan|pump|...}} color {{fixed|fading|rainbow|...}} {{00ff00}}`
