The ASUS Dual Radeon RX 6600 melds performance and simplicity like no other. It comes with an Axial-tech fan design that features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. It features Auto-Extreme Technology and a protective backplate to ensure all-around reliability. It's the perfect combination for a powerful plug-and-play experience. Newly designed for the latest generation of top-end ROG graphics cards, these fans feature a smaller hub that facilitates longer blades and a barrier ring to increase downward air pressure. An advanced onboard controller brings fans to a standstill when the GPU core temperature is below 60 Celsius, letting you enjoy light gaming in relative silence. As temps rise past the threshold, the fans automatically start up again. Dust is enemy number one for fans. It's easy to clean the blades, but taking the fan apart to remove dust that has made its way inside is not a simple task. The PCB is reinforced by an aluminum backplate that adds structural rigidity, helping to prevent flex and protect components and trace pathways from damage. 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, Overwatch, and PlayerUnknown'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. Experience stutter-free, tear-free gaming with AMD Radeon FreeSync Premium Pro technology, available on many ASUS monitors. The shroud features a subtle illuminated strip that creates a stylish accent for your build. The ASUS GPU Tweak II utility takes graphics card tuning to the next level. It allows you to tweak critical parameters including GPU core clocks, memory frequency, and voltage settings, with the option to monitor everything in real-time through a customizable on-screen display. Advanced fan control is also included along with many more features to help you get the most out of your graphics card. The ASUS Dual Radeon RX 6600 comes with 3 years of warranty.
