Key benefits — why you need this splitter Simplifies multidevice connections: splits a single 19pin internal connector into two 9pin outputs so you can connect extra RGB strips, fans or liquidcooling controllers without extra adapters. Reliable control and monitoring: robust conductive elements provide stable signal transmission and consistent data management, keeping fan speeds accurate and preventing signal loss during operation. Plugandplay compatibility: no drivers required; designed for broad motherboard support on the French market and compatible with USB 3.0 systems while providing a USB 2.0 extension for RGB/fan management. What it does 19pin dual 9pin design: converts a 19pin USB header into two separate 9pin outputs for connecting multiple RGB/fan devices and controllers. USB 2.0 extension included: supports common RGB and sensor control protocols that use USB 2.0 signaling while remaining compatible with USB 3.0 capable systems. Stable electrical performance: engineered with robust conductive elements to maintain consistent data flow and accurate fanspeed reporting under continuous use. Key attributes Function: internal splitter for RGB, fan and liquidcooling sensor management. Compatibility: supports a wide range of motherboards (French market), works with USB 3.0capable systems and provides USB 2.0 extension functionality; driver operation. Size and installation: compact internal design that conserves space inside the case and simplifies complex cable routing. Performance: stable signal transmission and precise fan speed control to avoid interruptions or degradation in device management. Typical use scenarios Building a liquidcooled PC: connect pump sensor, multiple radiator fans and RGB strips to a single 19pin header for centralized control and monitoring without extra controllers. Upgrading a midtower case: add RGB strips and an extra fan cluster to a motherboard with a single internal USB header, keeping cables neat and ensuring accurate RPM reporting. Advanced multidevice setups: split one internal connector to feed two controller hubs or multiple RGB/fan assemblies in systems with limited headers. What to expect Easy installation: plug into the motherboard's 19pin internal connector and attach up to two 9pin devices with no driver installation. Stable operation: consistent data handling for uninterrupted fan speeds and lighting control during extended use. Flexible integration: ideal for users who need to expand RGB and cooling hardware while preserving internal space and maintaining reliable performance.
