NVIDIA 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. 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. A lineup 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. Component and trace layouts have been optimized onto a short PCB to reduce power losses and let heat escape through a massive backplate vent. A high-quality diecast shroud and aluminum backplate prevent PCB flex and feature large vents to further increase heat dissipation. Aura-compatible ARGB lighting on the shroud adds a dash of customizable color 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.
