Gigabyte GeForce RTX 3090 GAMING OC 24G Graphics Card WINDFORCE 3X COOLING SYSTEMThe WINDFORCE 3X cooling system features 2x 90mm and 1X80mm unique blade fans, alternate spinning, 7 composite copper heat pipes, large copper plate direct touch GPU, 3D active fan and Screen cooling, which together provide high efficiency heat dissipation.ALTERNATE SPINNINGAlternate Spinning can reduce the turbulence of adjacent fans and increase air pressure.SMOOTH AIRFLOWGIGABYTE turns the adjacent fans in the opposite direction, so that the airflow direction between the two fans is the same, reducing the turbulence and enhancing the airflow pressure.3D ACTIVE FANThe 3D Active Fan provides semi-passive cooling, and the fans will remain off when the GPU is in a low load or low power game.UNIQUE BLADE FANThe airflow is spilt by the triangular fan edge, and guided smoothly through the 3D stripe curve on the fan surface.GRAPHENE NANO LUBRICANTGraphene nano lubricant can extend the life of sleeve bearing fan by 2.1 times, close to the life of double ball bearing, and is quieter.LARGE COPPER PLATE & HEAT-PIPEWith direct contact to the GPU and VRAM, the large copper plate combines the composite heat pipes to efficiently transfer heat generated from the interior cores to the heat sink.RGB FUSION 2.0With 16.7M customizable color options and numerous lighting effects, you can choose lighting effects or synchronize with other AORUS devices. EXTREME DURABILITY AND OVERCLOCKINGThe graphics card uses the 15+4 power phase design to allow the MOSFET to operate at lower temperature, and over-temperature protection design and load balancing for each MOSFET, plus the Ultra Durable certified chokes and capacitors, to provide excellent performance and longer system life.
