Core Clock

  • 1845 MHz (Reference card is 1770 MHz)






WINDFORCE 2X cooling system features 2x 100mm unique blade fans, alternate spinning fan, 2 composite copper heat pipes direct touch GPU and 3D active fan, together delivering an effective heat dissipation.



The GIGABYTE patent "Alternate Spinning" is the only solution that can solve the turbulent airflow of three fans. The biggest problem with the three fans is turbulence. Since the 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 middle fan in the opposite direction, so that the airflow direction between the two fans is the same, reducing the turbulence and enhancing the airflow pressure.



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.



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