Improved Axial-tech fans - A fresh spin

Bigger and better. Axial-tech fans spin on double ball bearings and have been enlarged, allowing 23% more air to pass through the graphics card. This reduces operating temperatures and noise emissions while increasing GPU performance.

Reverse rotation and 0dB technology - Well-managed cooling

The two side fans rotate counterclockwise to minimise turbulence and maximise airflow through the heatsink. All three fans completely stop when the GPU temperature drops below 50 degrees Celsius. This makes it possible to play less demanding games or work on non-stressful system tasks in relative silence. The fans restart when the temperature rises above 55 degrees Celsius. This is regulated according to the fan speed curve and the user enjoys a balance between performance and noise level when working or playing.

3.5-slot design - Solid construction and multiple fins

The heatsink with a customised design is large in size to effectively absorb heat from the GeForce RTX 4090 GPU, which is then effectively dissipated by three Axial-tech fans.

Patented vapour chamber - Phase change solution

The vapour chamber with milled paths allows the heatpipes to be lowered without compressing them flat, enabling more efficient heat transfer to the fin set. Compared to conventional solutions with a combination of vapour chamber and heatpipes, this efficient set-up reduces GPU temperatures by up to 5 degrees Celsius at a thermal load of 500 W.

High-performance power supply - First response system

Digital power control, a set of high-current power stages and a line of capacitors with a life span of 15,000 hours provide huge power reserves, so you enjoy stability when overclocking performance.

Compact PCB - Robust design

Component layout and pathways have been optimised on a short PCB, resulting in less power loss and allowing heat to escape through the large rear panel vent.

Metal exoskeleton - Exceptional structural rigidity

High-quality, cast-formed subframe, shield and backplate firmly stiffen the PCB and strategically control airflow.

FanConnect II - Connect additional fans

The two PWM FanConnect slots provide additional flexibility for personalised configurations. You can connect the case fans directly to the graphics card and tune their speed curve based on CPU and graphics card temperatures, providing additional intake or exhaust airflow for demanding 3D tasks.

Reinforcements - Additional benefits

The graphics card bracket provides additional stability to the critical connection between the PCB and the heat spreader. The rear I/O panel cover is made of stainless steel to prevent corrosion in humid climates and to allow better attachment of the card. Placed in a practical location, the Dual Bios switch allows quick selection of Performance and "Quiet" profiles, which regulate the speed of the Axial-tech fans.

Power detection - Quick diagnosis

Check if the power supply unit is worthy of your GPU. ROG Strix GeForce RTX 4090 graphics cards are equipped with a quick-diagnosis circuit that constantly monitors the power input from the power unit and uses virtually positioned LEDs to indicate problems with voltage regulation or cable connections.
