40% More Heat Dissipation Area

Up to 30% Cooler and 3X Quieter Gaming Performance because New AREZ Strix graphics cards are constructed with a wider 2.5-slot width which requires 3 free slots. It is worth it because it provides 40% more heat sink surface for heat dissipation compared to previous 2-slot designs for dramatically cooler and quieter performance.

MaxContact Technology: 2X More Contact with GPU for Improved Thermal Transfer
MaxContact is an industry-first GPU cooling technology, featuring an enhanced copper heat spreader that directly contacts the GPU. MaxContact utilizes precision machining to provide a surface that makes up to 2X more contact with the GPU than traditional heat spreaders, resulting in improved thermal transfer.

Patented Wing-Blade Design: Max Air Flow with 105% More Air Pressure
Patented wing-blade fans delivers maximum air flow and 105% greater static pressure over the heat sink, while operating at an up to 3X quieter volume than reference cards.

0dB Technology: Game in Complete Silence
Innovative 0dB technology stops the fan completely when the GPU temperature remains below a set level of 55° C, letting you enjoy light gaming in complete silence.

IP5X-Certified Dust Resistance: Longer Fan Lifespan
The fans in AREZ Strix graphics cards are certified under the International Protection Marking (IP code) as IP5X dust resistant for improved reliability and a longer lifespan. This stringent certification process ensures AREZ Strix graphics cards provide optimal fan performance, even under severe conditions.

ASUS FanConnect II: Optimal System Cooling
ASUS FanConnect II features two 4-pin, hybrid-controlled headers that can be connected to both PWM and DC system fans for optimal system cooling. The connected fans reference both the GPU and CPU, operating automatically based on the one with the higher temperature. A comprehensive set of tuning options allow you to tune fan speeds for efficient cooling.

GPU Tweak II lets you easily set these ASUS FanConnect II modes:

  • Auto Mode:
    Chassis fan speeds reference GPU temperatures and operate based on the default factory setting
  • Manual Mode:
    Allows you to set a fixed speed for connected fans
  • User-defined Mode:
    Allows you to set chassis fans to reference either the CPU or GPU temperature to determine rotational speed. Additionally, a smart, automatic calibration routine senses the controllable range of connected fans and allows you to fine-tune speeds for efficient cooling and low noise

Auto-Extreme Technology: Industry-only 100% Automated Production Process

All ASUS graphics cards are now produced using Auto-Extreme Technology, an industry-exclusive, 100% automated production process that incorporates premium materials to set a new standard of quality.

Auto-Extreme Technology ensures consistent graphics card quality as well as improved performance and longevity. Since the introduction of Auto-Extreme technology, reliability has improved by 30%! This new manufacturing process is also environmentally friendly, eliminating harsh chemicals and reducing power consumption during construction by 50%.

12+1 Phase Super Alloy Power II: Enhanced Durability and Efficiency
ASUS engineers have integrated premium alloy components into their graphics card designs to reinforce overall reliability. Super Alloy Power II components greatly enhance efficiency, reduce power loss and achieve thermal levels that are approximately 50% cooler than previous designs.


Featuring Aura RGB Lighting on both the shroud and backplate, AREZ Strix graphics cards are capable of displaying millions of colors and six different effects for a personalized gaming system. AREZ Strix graphics cards also feature ASUS Aura Sync, RGB LED synchronization technology that enables complete gaming system personalization when the graphics card is paired with an Aura-enabled gaming motherboard.
