Easy to use: enables integration of water cooling RGB and fan sensors through a 19pin to double 9pin design with USB2.0 expansion for connecting multiple devices. Compatible with a wide range of motherboards for flexible use and reliable operation. Precise fan control: uses conductive components for stable signal transmission. Supports accurate RGB management and fan speed monitoring without interruptions. Comprehensive applicability: this 19 pin USB 3.0 female connector provides plugandplay setup with no driver requirements and is compatible with RGB fans and water cooling devices to fit seamlessly into motherboards with 19 pin ports, increasing convenience and performance. Space saving design: splits a 19pin input into two 9pin outputs for RGB and fan devices, improving internal layout efficiency. Flexible splitting options provide maximum hardware compatibility. Use scenarios Custom PC with water cooling and RGB fans: connect RGB lighting, fan sensors, and cooling components through the 19pin to dual 9pin splitter and use the USB2.0 expansion to link multiple devices to a compatible motherboard for centralized control and reliable operation. Upgrading an older motherboard: plug and play with the 19pin USB 3.0 female connector, no driver required, enabling RGB and fan control for compatible RGB fans and water cooling devices that fit 19pin ports. Spaceconstrained or neatly routed builds: leverage the spacesaving design to split a single 19pin input into two 9pin outputs, simplifying cable management and maximizing hardware compatibility in compact systems.
