ASUS Phoenix Radeon RX 6400 4GB GDDR6 Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. Dual ball fan bearings can last up to twice as long as sleeve bearing designs. A stainless steel bracket is harder and more resistant to corrosion. A 144-hour validation program puts cards through a series of stringent tests to ensure compatibility with the latest games Auto-Extreme Technology uses automation to enhance reliability.   Packs a Punch The ASUS Phoenix Radeon RX 6400 derives its name from a high performance output in a robust package. A large single fan takes advantage of our Axial-tech fan design and a dual-ball bearing fan that lasts twice as long as sleeve-bearing alternatives. To raise the bar, each card is manufactured using our fully-automated Auto-Extreme Technology manufacturing process and put through a 144-hour gaming stress test. If you're looking for a long-lasting companion to power you through years to come, look no further than the ASUS Phoenix Axial-tech Fan Design Better, faster, stronger A large Axial-tech fan features a smaller hub that facilitates longer blades and a barrier ring to increase downward air pressure.

Auto-Extreme Technology Precision automated manufacturing Auto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption, and a more reliable product overall. Stainless Steel Bracket Steel yourself The mounting bracket of the Phoenix has been beefed up with 304 Stainless Steel that is harder and more resistant to corrosion. 144-hour Validation Program “Extensive” may be an understatement Each card must meet rigorous performance and reliability standards before it ships. Performance and stress tests are run with the latest chart-topping titles like Fortnite, League of Legends, Over watch, and Player Unknown's Battlegrounds. We also carry out reliability trials that include a 144-hour stability test and a series of 3DMark benchmarking runs to ensure the card performs well when pushed to the limits.
