Thanks to the latest AMD RDNA™ 2 architecture, the ASUS Dual Radeon™ RX 6400 combines dynamic thermal performance with broad compatibility. Advanced cooling solutions of flagship graphics cards, including two Axial-tech fans for maximum airflow to the heatsink, are housed in a 20 cm long dual-slot card, providing more power in a smaller space. All these enhancements make the ASUS Dual an ideal choice for gamers who need powerful graphics performance in a compact case. Product Description: ASUS Radeon RX 6400 4GB GDDR6 DUAL DUAL-RX6400-4G **Axial-tech Fan Design** Two proven Axial-tech fans feature a smaller hub, allowing for longer blades and a barrier ring that increases air pressure at the bottom. **0dB Technology** To eliminate unnecessary noise, the stop mode halts all fans when the GPU temperature drops below 52 degrees and power consumption is low. **Dual Ball Fan Bearings** Different types of bearings have unique advantages and disadvantages. Ball bearings stand out for their durability and can last twice as long as sleeve bearings. **2-Slot Design** The carefully considered layout of the shroud, heatsink, and heat pipes allows the two Axial-tech fans to effectively utilize the case's side panel ventilation and provide thermal performance that belies the card's size. **Auto-Extreme Technology** Auto-Extreme Technology is an automated manufacturing process that sets new industry standards by allowing all soldering to be done in a single pass. This reduces thermal strain on components and avoids the use of aggressive cleaning chemicals, which lessens environmental impact, lowers energy consumption, and enhances overall product reliability. **Protective Backplate** The printed circuit board is reinforced with an aluminum backplate that adds structural rigidity, helps prevent bending, and protects components and traces from damage. **Stainless Steel Mounting Bracket** The Dual mounting bracket is reinforced with 304 stainless steel, which is harder and more resistant to corrosion.
