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 heat spreader.
To bolster the specialized roles of the center and auxiliary fans, the rotational direction of the center fan is reversed. This reduces air turbulence inside the cooling array for another boost to overall thermal performance. The fans also shut off completely when card power consumption is low and the GPU temperature falls beneath 50 Celsius, keeping noise levels down when the system is under a light load.
To get heat into the heatsink array efficiently, so that it can be whisked away by the powerful Axial-tech fans, we use a manufacturing process that improves the surface smoothness of the heatspreader at the microscopic level. The extra flatness allows for better contact with the die, helping to enhance 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.
Top-shelf capacitors, chokes, and MOSFETs are selected to effortlessly deliver hundreds of watts at a millisecond's notice. The Super Alloy Power II parts are soldered to the PCB using our advanced Auto-Extreme automated manufacturing process. Smooth joints on the rear of the PCB and the elimination of human errors ensures each graphics card meets our rigorous specifications.
The rear of the card sports two PWM FanConnect headers that 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, providing extra intake or exhaust for demanding 3D tasks.
In addition to under-the-hood design changes, the ROG Strix features a new face with metal accents that mirror the design aesthetic of ROG and ROG Strix motherboards. Textured accents in a greyscale colorway blend seamlessly into subtle builds or make a striking impact while the card is vertically mounted and lit by chassis LEDs.
It's cooler out back
Flipping the card around reveals more design improvements. A wide backplate vent and shortened PCB allow hot air to escape towards chassis exhaust fans instead of being recycled back into the cooler. 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.
Careful attention has been paid to the front of the GPU, as it's the most visible part of the card in typical configurations. A new addressable RGB element can be customized with Armoury Crate to create a uniform look along with other ROG components. To fulfill the power demands of the GeForce RTX 3070 Ti, three 8-pin power connectors are present, along with an onboard circuit that monitors PSU rail voltage. The circuit is fast enough to catch any transients that result in the rail voltage dropping too low. If that happens, a red LED will light up to indicate a power supply issue. The Strix's reinforced metal frame is also visible here, adding a literal layer of durability.
