WINDFORCE 2X COOLING SYSTEM
WINDFORCE 2X cooling system features 2x 90mm unique blade fans, alternate spinning fan, a composite copper heat pipe direct touch GPU and 3D active fan functionality, together delivering an effective heat dissipation capacity for higher performance at lower temperatures.

ALTERNATE SPINNING
The 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 and 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 and enhancing the airflow pressure.

UNIQUE BLADE FAN
The airflow is spilt by the triangular fan edge, and guided smoothly through the 3D stripe curve on the fan surface, effectively enhancing the airflow.

3D ACTIVE FAN
The 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. It allows gamers to enjoy gameplay in complete silence when the system is running light or idle.

HEAT PIPE DIRECT TOUCH GPU
The shape of the pure copper heat pipe maximizes the direct contact area with the GPU, enhancing heat transfer. The heat pipe also covers the VRAM through a large metal plate contact to ensure proper cooling.

COMPOSITE HEAT-PIPE
The composite heat-pipe combines thermal conductivity and phase transition to efficiently manage the heat transfer between two solid interfaces which increases cooling capacity.

EXTREME DURABILITY AND OVERCLOCKING
The graphics card uses the 4+2 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. (Reference card is 3+1 power phase)

PROTECTION BACK PLATE
The back plate not only provides an aesthetical shape, but also enhances the structure of the graphics card to provide complete protection.

IN TOTAL COMMAND
The actual software UI and functionalities depend on each device model.

AORUS ENGINE
The cutting edge intuitive interface allows you to adjust the clock speed, voltage, fan performance and power target in real-time according to your game’s requirements.
