LHR Version 3D Active Fan providing semi-passive cooling RGB Fusion 2.0 with 16.7M customizable colour options Extreme durability & overclocking The Windforce 2X cooling system features 2X100mm unique blade fans alternate spinning 4 composite copper heat pipes direct touch GPU 3D active fab & Screen cooling whihc together provide high efficiency heat dissipation. Gigabyte turn the adjacent fans in the oppersite direction so that the airflow direction between the two fans is the same reducing the turbulence & enhancing the airflow pressure. The 3D Active Fan provides semi-passive cooling & the fans will remain off when the GPU in a low load of low power game. Unique Blade Fan where airflow is split by the triangular fan edge & guided smoothly through the 3D stripe curve on the fan surface. Graphene nano lubricant can extend teh life of fan by 2.1 times close to the life of double ball bearing & is quieter. Screen cooling with extended heatsink design allows airflow to pass through providing better heat dissipation. The shape of the pure copper heat pipes maximizes teh direct contact area with the GPU. The heat pipe also covers the VRAM through a large metal plate contact to ensure proper cooling.RGB Fusion 2.0 with 16.7M customizable colour options & numerous lighting effects you can choose lighting effects or synchronize with other AORUS devices. Extreme durability & overclocking the graphics card uses the better power phrase design to allow the MOSFET to operate at lower temperature & over-temperature protection design & load balancing for each MOSFET plus the ultra durable certified chokes & capacitors to provide excellent performance & longer system life. This Card is the LHR (Lite Harsh Rate) version..
