Features Radeon RX 6400 4GB GDDR6 Boost Clock: 2607MHz HDMI x 1 DP x 1 2x Fans. 2x Fun. Featuring the latest AMD RDNA™ 2 architecture, ASUS Dual Radeon™ RX 6400 fuses dynamic thermal performance with broad compatibility. Advanced cooling solutions from flagship graphics cards — including two Axial-tech fans for maximizing airflow to the heatsink — are packed into the 20 cm long, 2-slot card, delivering more power in less space. These enhancements make ASUS Dual the perfect choice for gamers who want heavyweight graphics performance in a compact build. Axial-tech Fan Design Better, faster, stronger Two tried-and-true Axial-tech fans feature a smaller hub that facilitates longer blades and a barrier ring to increase downward air pressure. 0dB Technology Quiet intelligence To eliminate unnecessary noise, a stop mode halts all fans when the GPU temp falls below 52 degrees and power consumption is low Dual Ball Fan Bearings 2x longer lifespan Different bearing types have unique pros and cons. Ball bearings excel at durability and can last up to twice as long as sleeve bearing designs. 2-slot Design Sink your heat into this A carefully designed shroud, heatsink, and heatpipe layout allows the two Axial-tech fans to leverage chassis side-panel ventilation and deliver thermal performance that belies the card’s size. 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
