Axial-tech Upgrades A Fresh Spin Bigger and better. Axial-tech fans spin on dual-ball bearings and have been scaled up to propel 23% more air through the card, setting the stage for lower temperatures, less noise, and higher performance. Reverse Rotation and 0dB Technology Orchestrated Chill The two side fans spin counterclockwise to minimize turbulence and maximize air dispersion through the heatsink. All three fans come to a standstill when GPU temps are below 50 Celsius, letting you play less-demanding games or perform light tasks in relative silence. Fans start up again when temps are over 55 C, referencing a speed curve that balances performance and acoustics for work or play. 3.5-slot Design Through Thick and Fin The custom sink is generously sized and structured to soak up heat from the GeForce RTX 4090 GPU so that it can be efficiently whisked away by the three Axial-tech fans. Patented Vapor Chamber Phase Changer A vapor chamber featuring milled pathways lets the heatpipes sink in without being pressed flat, allowing heat to be carried more efficiently to the fin stack. In comparison to conventional vapor chamber and heatpipe combos, this potent pairing reduces GPU temperature by up to 5 Celsius when subjected to a 500W thermal load. Premium Power Delivery 1st Responder Digital power control, an array of high-current power stages, and a lineup of 15K caps ensure massive reserves to reliably push performance boundaries. Hook up Two PWM FanConnect headers provide additional DIY flexibility. Chassis fans can be directly attached to the card and tuned with a curve that is based on CPU and GPU temperatures, delivering extra intake or exhaust for demanding 3D tasks. Additional Perks A GPU bracket provides extra stability to the critical connection between die and heat spreader. The rear I/O bracket is made from stainless steel to prevent corrosion in humid climates and provide a more resilient mount. A conveniently placed Dual Bios switch allows quick selection between “performance” and “quiet” speed profiles for the Axial-tech fans. Quick Diagnosis Know if your PSU is worthy. ROG Strix GeForce RTX 4090 graphics cards feature a high-speed circuit that constantly monitors input power from the PSU and utilizes conveniently placed LEDs to indicate voltage regulation issues and cable connection problems. Reliability Boost 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. Symphony of Light Aura-compatible ARGB lighting elements on the shroud and rightmost perimeter of the card provide endless possibilities for personalization with color or functional effects.
