The GIGABYTE “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.
