It’s optimized for delivering excellent gaming experience with stylish and streamlined design. Stylish Metal Backplate Solid, Fancy, Cool. Designed to avoid PCB bending. The fancy outlook makes the graphic card more legendary in visual. It also helps to enhance cooling with the premium thermal pads equipped backside. Striped Axial Fan Designed For Enhanced Airflow. ASRock’s custom Striped Axial Fan delivers enhanced airflow to optimize cooling from not only the stripe structure on each fan blade but also the polishing surface on the bottom side. 0dB Silent Cooling Spin For Cooling, Stop For Silence. The fan spins when the temperature goes high for the optimal cooling, and stops when the temperature goes low for the complete silence. Ultra-fit Heatpipe Consolidated to Maximize the Contact. The heatpipes are consolidated to maximize the contact among each others and also the GPU baseplate for the optimized heat dissipation. Copper Base Maximize GPU Contact Area. With premium copper base heatsink design, the direct contact area to the GPU would be maximized to improve thermal transfer effectively. Nano Thermal Paste Perfect Thermal Teamwork. Eliminate the gaps in the contact area to maximize heat transfer and thermal efficiency. Premium Thermal Pad Better Heat Transfer. The premium thermal pad helps to transfer the heat of the components to the heatsink, improving heat dissipation. Precise Screw Torque Optimized Mounting Pressure. ASRock adopts precise screw torque when assembling its graphics cards to optimize the cooler mounting pressure to improve thermal efficiency while avoiding damage to GPU die.
