Key Features
- The GPU water block is compatible with ASUS ROG Astral GeForce RTX5090 O32GB and ROG Astral GeForce RTX5090 D 32GB graphics cards (for detailed model information, please refer to the compatibility list). Please check the PCB picture to ensure compatibility. Avoid buying mistakes, or contact the seller.
- The GPU water block features a T2 copper baseplate with a full-coverage design, increasing both water flow coverage and heat dissipation area. Sufficient mate rials, using single-layersealing ring design to effectively reduce the risk of liquid leakage.
- The 0.3mm spray micro-waterway design, features up to 56 waterways, effectively expanding the heat absorption area and delivering robust cooling performance. Base thickness of 0.35mm effectively reduces the thermal resistance value of the copper plate and improvesthermal conductivity efficiency.
- Customized exclusive backboard. Matte texture craftsmanship, using high-quality aluminum material, with sandwich installation providingall-round protection.
- To reduce the weight of the water block and prevent PCB deformation, a nickel-plating surface treatment process is employed. With a coating thickness of just 0.001-0.002mm, this reduces thermal resistance while also providing more effective corrosion protection.
