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: *(this snap is unofficial and is not endorsed by the upsteam project)* **Examples:** List connected compatible devices: ``` $ liquidctl list Device #0: Corsair HX750i Device #1: Corsair Hydro H100i v2 ``` See the power output for a compatible power supply unit: ``` $ liquidctl --match HX750i status Corsair HX750i ├── Current uptime 11:03:54 ├── Total uptime 735 days, 7:03:54 ├── Temperature 1 43.2 °C ├── Temperature 2 36.8 °C ├── Fan control mode Hardware ├── Fan speed 0 rpm ├── Input voltage 230.00 V ├── +12V OCP mode Multi rail ├── +12V output voltage 12.14 V ├── +12V output current 3.25 A ├── +12V output power 38.00 W ├── +5V output voltage 5.02 V ├── +5V output current 3.00 A ├── +5V output power 15.00 W ├── +3.3V output voltage 3.28 V ├── +3.3V output current 0.81 A ├── +3.3V output power 2.50 W ├── Total power output 52.00 W ├── Estimated input power 61.00 W └── Estimated efficiency 85 % ``` Set the fan thresholds for a hydro cooler: ``` $ liquidctl --match hydro set fan speed 0 0 100 0 45 55 50 60 55 75 60 100 ``` ### Package name * liquidctl --- ### License * GPL-3.0-or-later --- ### Last updated * 30 March 2023 - latest/stable * 17 June 2026 - latest/edge --- ### Websites * [github.com/degville/liquidctl-snap](https://github.com/degville/liquidctl-snap "https://github.com/degville/liquidctl-snap") --- ### Contact * [graham.morrison@canonical.com](mailto:graham.morrison@canonical.com "mailto:graham.morrison@canonical.com") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/liquidctl/rhel#report-snap-modal) --- ## Enable snaps on Red Hat Enterprise Linux and install liquidctl Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` Either log out and back in again or restart your system to ensure snap’s paths are updated correctly. ### Install liquidctl To install liquidctl, simply use the following command: ``` sudo snap install liquidctl ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
