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.
