Dual Fan Design

Two fans that provide strong cooling performance and make your gaming rig stay cool. It’s optimized for delivering excellent gaming experience with stylish and streamlined design.

Stylish Metal Backplate

Solid, Fancy, Cool.

Designed to avoid PCB bending. The fancy outlook makes the graphic card more legendary in visual. It also helps to enhance cooling with the premium thermal pads equipped backside.

Striped Axial Fan

Designed For Enhanced Airflow.

ASRock’s custom Striped Axial Fan delivers enhanced airflow to optimize cooling from not only the stripe structure on each fan blade but also the polishing surface on the bottom side.

0dB Silent Cooling

Spin For Cooling, Stop For Silence.

The fan spins when the temperature goes high for the optimal cooling, and stops when the temperature goes low for the complete silence.

Ultra-fit Heatpipe

Consolidated to Maximize the Contact.

The heatpipes are consolidated to maximize the contact among each others and also the GPU baseplate for the optimized heat dissipation.

Copper Base

Maximize GPU Contact Area.

With premium copper base heatsink design, the direct contact area to the GPU would be maximized to improve thermal transfer effectively.

Nano Thermal Paste

Perfect Thermal Teamwork.

Eliminate the gaps in the contact area to maximize heat transfer and thermal efficiency.

Premium Thermal Pad

Better Heat Transfer.

The premium thermal pad helps to transfer the heat of the components to the heatsink, improving heat dissipation.

Precise Screw Torque

Optimized Mounting Pressure.

ASRock adopts precise screw torque when assembling its graphics cards to optimize the cooler mounting pressure to improve thermal efficiency while avoiding damage to GPU die.

Dr. MOS

Dr.MOS is the integrated power stage solution which is optimized for synchronous buck-set down voltage applications! Intelligently delivering higher current and driving up to 50A continuous current for each phase, thus providing improved thermal result and superior performance.

Premium 90A Power Choke

Compared to traditional chokes, ASRock’s premium 90A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the graphics card.

Matte Black PCB

A new mysterious matte black and copper color scheme to match the prestigious components on ASRock's high-end graphics card.

High Density Glass Fabric PCB

High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the graphics card against electrical shorts caused by humidity.
