Powerful Impact The ASUS Phoenix Radeon RX 6400 gets its name from its high performance in a reliable chassis. The large single fan takes advantage of our Axial-tech fan design and dual ball bearing fan, which lasts twice as long as alternative bearing options. To raise the bar, each card is made using our fully automated production process, Auto-Extreme Technology, and undergoes a 144-hour gaming stress test. If you're looking for a durable companion that will keep you powered for years to come, consider the ASUS Phoenix. Axial-tech Fan Design The large Axial-tech fan features a smaller hub that helps increase the length of the blades and a barrier ring to increase downward air pressure. Dual Ball Bearing Fans Different types of bearings have unique pros and cons. Ball bearings excel in durability and can last twice as long as sliding bearings. 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, resulting in a lower environmental impact, reduced power consumption, and increased overall product reliability. Stainless Steel Bracket The Phoenix mounting bracket has been reinforced with 304 stainless steel, which is harder and more corrosion-resistant. 144-Hour Validation Program Each card must meet strict performance and reliability standards before being released for sale. Performance tests and stress tests are conducted using the latest top-charting games such as Fortnite, League of Legends, Overwatch, and PlayerUnknown's Battlegrounds. We also conduct reliability testing, including a 144-hour stability test and a series of 3DMark benchmark tests to ensure the card performs well under maximum load.
