The ’liquidctl list’ command lists all the available liquid coolers connected to the system.
Example output:
Device 1: Corsair H100i Pro
Device 2: NZXT Kraken X62
Use case 2: Initialize all supported devices
Code:
sudo liquidctl initialize all
Motivation:
This use case is used to initialize all the supported liquid cooler devices connected to the system.
Explanation:
The ‘sudo liquidctl initialize all’ command initializes all the supported liquid cooler devices connected to the system. This is useful when users want to ensure all the devices are properly initialized before using them.
Example output:
Initialization complete.
Use case 3: Print the status of available liquid coolers
Code:
liquidctl status
Motivation:
This use case is used to check the current status of the available liquid coolers.
Explanation:
The ’liquidctl status’ command prints the status of all the available liquid coolers, including fan speeds, temperatures, and other relevant information.
Example output:
Device: Corsair H100i Pro
Fan Speed: 1200 RPM
Temperature: 40°C
Device: NZXT Kraken X62
Fan Speed: 1000 RPM
Temperature: 35°C
Use case 4: Match a string in product name to pick a device and set its fan speed
Code:
liquidctl --match string set fan speed 20 0 50 50 70 100
Motivation:
This use case allows users to set the fan speed of a specific liquid cooler based on a string match in the product name. It provides finer control over the cooling performance.
Explanation:
The ’liquidctl –match string set fan speed 20 0 50 50 70 100’ command matches the specified string in the product name of a liquid cooler and sets its fan speed based on the specified temperature thresholds and fan speeds. In this example, the fan speed is set to 0% at 20°C, 50% at 50°C, and 100% at 70°C.
Example output:
Fan speed for Corsair H100i Pro set successfully.
Conclusion:
The ’liquidctl’ command provides users with a versatile tool to control liquid coolers. With the use cases showcased in this article, users can list available devices, initialize supported devices, print the status of available liquid coolers, and set specific parameters for individual liquid coolers. This flexibility empowers users to customize their liquid cooling system for optimal performance.
