Easy to use: provides support for water cooling RGB and fan sensors through a 19pin to double 9pin structure with USB2.0 expansion capabilities to connect various peripherals, and it adapts to common motherboard configurations for reliable operation. Reliable data and control: delivers consistent RGB control and precise fan speed monitoring through durable conductive materials that ensure stable data acquisition and improved device performance. Wide compatibility: a 19pin USB 3.0 female connector allows instant connections with RGB fans and water cooling systems without drivers, and offers broad compatibility with motherboards featuring dedicated 19pin connectors to ensure reliable operation. Flexible port management: splits a 19pin USB 3.0 header into two 9pin outputs, enabling RGB lighting or fans to be connected while optimizing internal organization through flexible splitting for better cable management and compatibility with different devices. Use scenarios Scenario 1: In a gaming PC with multiple RGB fans and a water cooling loop, connect RGB sensors and devices via the 19pin to two 9pin split to simplify wiring and avoid driver installation. Scenario 2: For a system integration project using a motherboard that has a dedicated 19pin header, install RGB fans and cooling components quickly with plugandplay connectivity and improved cable management. Scenario 3: In compact builds or cases with tight space, use the dual 9pin outputs to distribute connections cleanly, maintaining airflow and aesthetics while ensuring reliable performance and compatibility.
