Easy to operate: Converts a 19pin USB 3.0 header to two 9pin outputs, with USB2.0 expansion capability to connect multiple peripherals. This supports water cooling RGB and fan sensor connections and adapts to mainstream motherboard setups. Consistent data maintenance: Uses endurable conductive materials to ensure dependable RGB control and precise fan speed monitoring, enhancing device performance seamlessly. Broad application: No drivers required. The 19pin USB 3.0 header offers plugandplay setup with wide compatibility for RGB fans and watercooling devices, conveniently fitting motherboards with 19pin ports for enhanced performance. Efficient port splitting: Transforms a single 19pin USB 3.0 header into two 9pin outputs, allowing multiple RGB or fan devices while maintaining optimized internal configurations and adaptable port allocation. Use scenarios: In a end gaming PC with multiple RGB fans and a water cooling loop, this splitter enables synchronized RGB control and sensor monitoring without needing extra controllers. In a compact or spaceconstrained build, it expands RGB and fan connectivity while keeping a clean internal layout. On a testing bench or modding project, it allows connecting and testing multiple RGB devices and fan sensors with plugandplay simplicity and driver setup.
