. WINDFORCE 2X COOLING SYSTEMWINDFORCE 2X cooling system features 2x 90mm unique blade fans alternate spinning fan 2 composite copper heat pipes direct touch GPU & 3D active fan functionality together delivering an effective heat dissipation capacity for higher performance at lower temperatures.ALTERNATE SPINNINGThe GIGABYTE patent " Alternate Spinning" is the only solution that can solve the turbulent airflow of adjacent fans. Since the adjacent fans rotate in the same direction the airflow direction is opposite between the fans which will cause turbulent airflow & reduce heat dissipation efficiency. GIGABYTE turns the adjacent fans in the opposite direction so that the airflow direction between the two fans is the same reducing the turbulence & enhancing the airflow pressure.UNIQUE BLADE FANThe airflow is spilt by the triangular fan edge & guided smoothly through the 3D stripe curve on the fan surface effectively enhancing the airflow.3D ACTIVE FANThe 3D Active Fan provides semi-passive cooling & the fans will remain off when the GPU is in a low load or low power game. It allows gamers to enjoy gameplay in complete silence when the system is running light or idle.HEAT PIPES DIRECT TOUCHThe shape of the pure copper heat pipes maximize the direct contact area with the GPU enhancing heat transfer. The heat pipes also cover the VRAM through a large metal plate contact to ensure proper cooling.COMPOSITE HEAT-PIPESThe composite heat-pipes combines thermal conductivity & phase transition to efficiently manage the heat transfer between two solid interfaces which increases cooling capacity BUILT STRONGEXTREME DURABILITY & OVERCLOCKINGThe graphics card uses the 4+2 power phase 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.PROTECTION BACK PLATEThe back plate not only provides an aesthetical shape but also enhances the structure of the graphics card to provide complete protection..
