Easy to use and easy to install Supports water cooling RGB and fan sensors through a 19pin to double 9pin structure with USB2.0 expansion for connecting peripherals. Adapts to common motherboard configurations to deliver reliable, functionality. Reliable signal and precise control Provides stable signal transmission to maintain consistent data streams, enabling efficient RGB adjustments and accurate fan speed control for uninterrupted operation. Wide compatibility and driver operation The 19pin USB 3.0 female connector allows instant connections with RGB fans and water cooling systems without the need for drivers. Compatible with motherboards that feature dedicated 19pin connectors to ensure reliable operation. Flexible port management for easier setup Splits a 19pin USB 3.0 header into two 9pin outputs, enabling RGB lighting or fans to be connected while improving internal organization. Flexible splitting supports better cable management and compatibility with different devices. Use scenarios Scenario 1: Custom gaming PC with a water cooling loop and multiple RGB fans Use this adapter to connect RGB lighting and cooling sensors through a single header, ensuring coordinated lighting effects and consistent fan control without driver installation. Scenario 2: Motherboard with limited headers Expand USB2.0 and RGB connections by splitting a 19pin header into two 9pin outputs, enabling additional peripherals while maintaining tidy cable routing and reliable operation. Scenario 3: Small form factor or neatly organized builds Apply the dual 9pin outputs to separate RGB lighting and fan connections, improving cable management and compatibility with different devices without sacrificing performance.
