Convert a single motherboard 19pin USB 3.0 header into two usable 9pin connectors to expand connectivity for RGB devices, fans, and cooling components while keeping your build tidy and reliable. Key benefits Expand connectivity without extra headers: Split one 19pin header into two 9pin connectors so you can attach additional RGB fans, AIO watercoolers, fan sensors, or frontpanel USB devices using a 19pin to dual 9pin adapter. Stable signals and precise control: Built with quality conductive components to maintain consistent data streams, reliable fan speed reporting, and predictable RGB control for synchronized lighting and cooling. Fast, nofuss setup: Designed for standard 19pin motherboard headers and works driver. Plugandplay installation minimizes setup time and avoids software conflicts. Cleaner internal layout: Converts and duplicates the header functionality while reducing cable clutter for better airflow and easier maintenance. Clear features Function: Splits a 19pin USB 3.0 motherboard header into two 9pin connectors to support multiple peripherals and adapters. Compatibility: Designed for mainstream motherboards with standard 19pin headers; supports RGB lighting devices, fan sensors, watercooling components, and additional USB 2.0 ports via a 19pin to double 9pin adapter solution. Performance: Ensures dependable signal stability for uniform data transfer and accurate fan speed regulation through conductive components. Installation: Driver plugandplay operation; simple connection to the motherboard header and peripherals. Practical applications Building a gaming PC with several RGB fans and an AIO cooler: Use the adapter to connect both the cooler and multiple fans to a single 19pin header while keeping RGB lighting synchronized and fan monitoring accurate. Adding frontpanel or caseconnected USB 2.0 ports: Convert the 19pin header output to additional 9pin USB ports via the adapter solution to support legacy peripherals without changing motherboards. Small or compact builds where header space is limited: Duplicate header functionality to attach sensors and RGB devices while maintaining neat cable routing and airflow. Technical notes Converts a single 19pin USB 3.0 motherboard header into two 9pin connectors Supports RGB effects, fan sensors, watercooling components, and additional USB 2.0 ports via a 19pin to dual 9pin adapter Uses quality conductive components for signal stability and reliable fan/RGB control Driver plugandplay for quick installation Designed for compatibility with mainstream 19pin motherboard headers What you get A straightforward, reliable adapter solution that increases your motherboard's connector flexibility, stabilizes peripheral communications, and simplifies internal cable management without requiring drivers or complex setup.
