Easy to use - Supports water cooling RGB and fan sensors through a 19-pin to double 9-pin structure with USB2.0 expansion to connect various peripherals. It seamlessly adapts to common motherboard 19-pin configurations for optimal functionality. Consistent data maintenance - Delivers reliable RGB control and precise fan speed monitoring through durable conductive materials that ensure stable data acquisition and improved device performance. Wide compatibility - The 19-pin USB 3.0 female connector allows instant connections with RGB fans and water cooling systems without the need for drivers, and provides broad compatibility with motherboards that feature dedicated 19-pin connectors to ensure reliable operation. Improved port management - Splits a 19-pin USB 3.0 header into two 9-pin outputs, enabling RGB lighting or fans to be connected while optimizing internal organization. Flexible splitting enhances cable management and compatibility with different devices. Use scenarios - Custom PC with water cooling and RGB: Connect RGB fans and water cooling sensors via the 19-pin to double 9-pin split, use USB2.0 expansion for peripherals, and rely on driver-free operation for quick setup. - Multi-fan RGB build: Run separate RGB and fan connections through the two 9-pin outputs to improve cable management and maintain clean interior airflow and layout. - System upgrade or assembly in various motherboards: Use the 19-pin USB 3.0 female connector for immediate compatibility with compatible motherboards, enabling reliable operation without additional drivers.
