Cancel DirectCU Direct cooling for 20% cooler than reference Please check out our microsite for more details and downloads.If the GPU is the heart of a graphics card, then the cooling device would be its lungs. Without it, the graphics card would not be able to "breath" smoothly, causing it to break down or even cause the entire system to fail. For ultimate cooling, ASUS DirectCU thermal technology developed the ideal heat banishing copper in exclusively designed heat pipes for direct and fast heat dissipation. ASUS DirectCU technologyThick copper heatpipes are accurately positioned in direct contact with the GPU surface so heat is transported and dissipated efficiently to the heatsink - achieving a 20% cooler performance than reference. Since heat is carried away faster, fans can spin at a lower speed thus resulting in quieter performance than reference. Other brandsAn extra metal plate is placed between the heatpipes and GPU, slowing down heat transfer to the heatsink. Due to temperature build-up, the fan has to spin faster, leading to louder operating noise. Please check out our microsite for more details and downloads. Super Alloy Power 15% performance boost, 2.5 times longer lifespan, 35°C cooler operation The new and exclusive Super Alloy Power technology on ASUS graphics cards uses a special alloy formula which is highly-magnetic, heat-resistant and anti-corrosive. It delivers a more stable and quieter operation compared to the reference design – a welcome bonus sought after by performance seekers. 15% Performance BoostDuring overclocking, the Super Hybrid Engine acts as an intelligent controller to switch between high and low intensity power profiles in real time for 15% performance boost*. 2.5X Longer LifespanSuper Alloy Capacitor increases the card’s lifespan to 150,000 hours which is 2.5 times longer* than traditional capacitors. 35°C Cooler OperationsSuper Alloy components are reinforced with special alloy formula and manufactured under high temperature and pressure to deliver stable and noise-free operation. GPU Tweak Tweak and tune like a PRO Please check out our microsite for more details and downloads.Overclocking is made real-time and intuitive with ASUS GPU Tweak utility. It not only allows you to optimize clock speeds, voltage and fan speeds on up to four graphics cards independently or simultaneously, you can also select between GPU Tweak’s Standard or Advanced modes depending on your level of experience. On top of these exciting tools, ASUS gives you more: Sync GPU clocks and voltages for easier overclocking Automatically check and update driver and BIOS versions Get detailed specs and actual card status with GPU-Z 2D/3D switcher can lock the card in 3D for higher benchmarks Monitoring widget provides detailed multi-parameter info Please check out our microsite for more details and downloads.
