ASUS ROG STRIX RTX™ 3090 O24G OC GAMING
ROG Strix GeForce RTX™ 3090 buffed-up design with chart-topping thermal performance.
NVIDIA Ampere Streaming Multiprocessors: The building blocks for the world’s fastest, most efficient GPU, the all-new Ampere SM brings 2X the FP32 throughput and improved power efficiency.
2nd Generation RT Cores:Experience 2X the throughput of 1st gen RT Cores, plus concurrent RT and shading for a whole new level of ray tracing performance.
3rd Generation Tensor Cores: Get up to 2X the throughput with structural sparsity and advanced AI algorithms such as DLSS. Now with support for up to 8K resolution, these cores deliver a massive boost in game performance and all-new AI capabilities.
Axial-tech Fan Design has been tuned up with more fan blades and a reversed rotational direction for the center fan.
2.9-slot design expands cooling surface area compared to last gen for more thermal headroom than ever before.
Super Alloy Power II includes premium alloy chokes, solid polymer capacitors, and an array of high-current power stages.
GPU Tweak II provides intuitive performance tweaking, thermal controls, and system monitoring.
Our Axial-tech fan design has been optimized for a new, larger heatsink that features more fins and surface area than last gen. The blade count has been increased on all three fans, with 13 on the center fan and 11 on the auxiliary fans. The barrier ring on the side fans has been slimmed down to allow for more lateral intake and to provide better airflow through the cooling array. The center fan’s extra blades and full-height ring provide boosted static pressure to blast air directly onto the GPU heat spreader.
To bolster the specialized roles of the center and auxiliary fans, the rotational direction of the center fan has been reversed. This reduces airflow turbulence inside of the cooling array for another boost to the card’s overall thermal performance.
The sum of the ROG Strix’s cooling innovations results in lower fan speeds and raises the performance threshold for achieving a sub-55 degree GPU temp, at which point the fans can shut off completely. Builders seeking quiet performance will be pleased.
To get heat up off the die and into the heatsink array to benefit from the new fan design requires special attention. We use a manufacturing process that polishes the surface of the heat spreader to improve smoothness at the microscopic level. The extra flatness allows for better contact with the die for improved thermal transfer.
The heat spreader draws heat up into heatpipes that carry it through a fin stack that fills a large 2.9-slot footprint. Increasing the heatsink size compared to the last generation provides more thermal headroom to account for the new high-performance chipset.
IT’S COOLER OUT BACK
Flipping the card around reveals more design improvements. A wide backplate vent and shortened PCB allows hot air to escape towards chassis exhaust fans instead of being recycled by the GPU’s circulating cooler design. A GPU bracket provides extra stability to the critical connection between die and heat spreader. The I/O bracket is made from stainless steel to protect ports and provide a more secure mount. A conveniently placed Dual Bios switch allows quick selection between “performance” and “quiet” mode for basic customization of the card’s default behavior without software.
