ASUS GeForce RTX 5090 Republic of Gamers Astral OC Graphics Card

The ROG Astral features a revolutionary four-fan design, which creates a powerful vertical airflow channel that boosts air pressure by up to 20%. This results in optimal thermal performance that dramatically lowers GPU temperatures and minimizes hotspots, enabling high clock speeds. The addition of a fourth fan means more densely packed heat sink fans for increased cooling potential.

A patented vapor chamber designed with milled pathways allows heatpipes to sink in without flattening, boosting heat dissipation efficiency. The MaxContact design effectively increases the surface area of the GPU heat spreader by 5% for improved thermal efficiency. By melting to effectively fill the gaps between the GPU and the thermal module, a premium phase-change GPU thermal pad provides optimal thermal conductivity and enhanced heat dissipation, ensuring optimal performance and longevity for graphics cards under heavy loads.

FanConnect II

There are two PWM FanConnect headers that provide additional DIY flexibility.

Chassis fans can be directly synced with the ROG Astral OC.

The chassis fans can also be tuned with a curve that is based on CPU and GPU temperatures, delivering extra intake or exhaust for demanding 3D tasks.

Dual BIOS

Do you prioritize low core temps or low noise levels?

Performance mode lets the fans spin up to keep the card running cool all the time.

Quiet mode keeps the same power target and top-end settings while offering a less aggressive fan curve for quieter operation at medium temperatures.

Aura Sync

With indirect Aura Sync ARGB lighting, the ROG Astral OC provides endless possibilities for personalization with color or functional effects. Aura is a one-stop shop for controlling anything RGB on your system.

Depending on your platform and accessories, you can use the Aura Sync utility to sync your GPU lights with your keyboard, monitor, motherboard, case lights, and more.
