The ROG Strix GeForce RTX 4090 brings a whole new meaning to going with the flow. Inside and out, every element of the card gives the monstrous GPU headroom to breathe freely and achieve ultimate performance. The unleashed reign of the NVIDIA Ada Lovelace architecture is here. 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. 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. Digital power control, an array of high-current power stages, and a lineup of 15K caps ensure massive reserves to reliably push performance boundaries. Component and trace layouts have been optimized onto a short PCB to reduce power losses and let heat escape through a massive backplate vent. A high-quality diecast frame, shroud, and backplate tightly brace the PCB and strategically steer airflow. 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. 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.
