Axial-tech Upgrades
A Fresh Spin
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.

Reverse Rotation and 0dB Technology
Orchestrated Chill
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 C, referencing a speed curve that balances performance and acoustics for work or play.

3.5-slot Design
Through Thick and Fin
The custom sink is generously sized and structured to soak up heat from the GeForce RTX 4090 GPU so that it can be efficiently whisked away by the three Axial-tech fans.

Patented Vapor Chamber
Phase Changer
A vapor chamber featuring milled pathways lets the heatpipes sink in without being pressed flat, allowing heat to be carried more efficiently to the fin stack. In comparison to conventional vapor chamber and heatpipe combos, this potent pairing reduces GPU temperature by up to 5 Celsius when subjected to a 500W thermal load.

Premium Power Delivery
1st Responder
Digital power control, an array of high-current power stages, and a lineup of 15K caps ensure massive reserves to reliably push performance boundaries.

Compact PCB
Packs a Punch
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
Ultra-rigid
A high-quality diecast frame, shroud, and backplate tightly brace the PCB and strategically steer airflow.
