Armed for flowNVIDIA Ada Lovelace architecture elevated by buffed cooling and power delivery, and backed with an arsenal of rugged reinforcements to cover your six. Lock, load, and dominate with the TUF Gaming GeForce RTX 4090.Axial-tech upgradesBigger 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.Well-maintained formationThe 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 designA generously sized heatsink efficiently soaks up heat from the GeForce RTX 4090 GPU, allowing it to be whisked away by the three Axial-tech fans.Military-grade 20K capacitorsA lineup of capacitors rated to last many 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 PCBComponent and trace layouts have been optimized onto a short PCB to reduce power losses and let heat escape through a massive backplate vent.Metal exoskeletonA high-quality diecast shroud and aluminum backplate prevent PCB flex and feature large vents to further increase heat dissipation.Lock, load, and let the performance flowThe GeForce RTX 4090 gloriously presented on a backdrop of low noise and rugged durability.Auto-Extreme technologyAuto-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.
