AXIAL-TECH UPGRADES
Air Superiority
Bigger and better. Axial-tech fans spin on dual-ball bearings and have been scaled up to propel 23% more air through the card, setting the stage for lower temperatures, less noise, and higher performance.
NEW DIRECTION
Well-maintained Formation
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 Celsius, referencing a speed curve that balances performance and acoustics for work or play.
3.65-SLOT DESIGN
Phase That Blaze
A vapor chamber and generously sized heatsink combo efficiently soak up heat from the GeForce RTX 4090 GPU so that it can be whisked away by the three Axial-tech fans.
MILITARY-GRADE 20K CAPACITORS
A line-up of capacitors rated to last 20,000 hours at 105 Celsius brings higher temperature and ripple tolerance to the GPU power rail, arming the card for long-term deployment in challenging conditions.
Compact PCB
Component and trace layouts have been optimized onto a short PCB to reduce power losses and let heat escape through a massive backplate vent.
Metal Exoskeleton
A high-quality diecast shroud and aluminium backplate prevent PCB flex and feature large vents to further increase heat dissipation.
Auto-Extreme Technology
Auto-Extreme Technology is an automated manufacturing process that sets new standards in the industry by allowing all soldering to be completed in a single pass. This reduces thermal strain on components and avoids the use of harsh cleaning chemicals, resulting in less environmental impact, lower manufacturing power consumption, and a more reliable product overall.
Aura Sync
Aura-compatible ARGB lighting on the shroud adds a dash of customizable colour or functional effects to your build. Pair up with a vast range of compatible system components and coordinate the glow to create a theme that’s uniquely you.
Software Suite
Hardware and software come together to let you fully customize your experience and get the most out of your graphics card. GPU Tweak II allows for hardware tweaking and monitoring, and Quantum Cloud utilizes your spare GPU computing power to generate passive income.
