liquidctl

liquidctl is a command-line tool to monitor and control fan speeds, LED colour and pump volumes of specific power supplies, motherboards, graphics cards and cooling solutions.

To allow this snap access to your device(s), issue the following connection commands:

 sudo snap connect liquidctl:raw-usb
 sudo snap connect liquidctl:hardware-observe

For more information, see the upstream project repository: https://github.com/liquidctl/liquidctl
