Open Source Technical Declaration

CoolerLCD Linux is an independent open-source interoperability project created to provide native Linux support for USB HID cooler LCD screens using the 5131:2007 controller.

The project focuses on CPU cooler LCD displays sold under multiple brands and rebrands, including Vevor YC-01-SS-002 compatible units. Its purpose is to allow Linux users to display system information such as CPU temperature, GPU temperature, fan speed, pump speed, memory usage and time directly on the cooler screen without using Windows, Wine or vendor background software.

CoolerLCD Linux communicates with the device through the Linux hidraw interface and standard HID output reports. The project does not include vendor code, firmware, trademarks, proprietary binaries or modified vendor software. It exists strictly as an interoperability driver for Linux users.

This project is designed for transparency, auditability and long-term maintenance. Protocol notes, installation steps and compatibility information are intended to be documented publicly so users can understand what the driver sends to the device and how the Linux service operates.

Primary compatibility focus

• USB HID controller: 5131:2007
• Linux hidraw interface
• CPU cooler LCD screens
• Vevor YC-01-SS-002 compatible LCD units
• Rebranded circular AIO cooler displays using the same HID controller

Project principles

• No Windows dependency
• No Wine dependency
• No proprietary vendor code included
• No telemetry
• No cloud requirement
• No unnecessary root execution
• Open protocol documentation where possible

Maintenance status

CoolerLCD Linux is maintained as an open-source hardware interoperability project. Updates are published when compatibility, security, documentation or Linux support improvements are required.
