The 78000GTX card from GIGABYTE is a standard reference card in many respects. GIGABYTE uses the standard 30-pin radial fan to cool the graphics unit. The heat sink is similar to the reference card, even down to the pattern of the cut of the design. GIGABYTE's name adorns the heat sink instead of NVIDIA's on the reference design. There are designs out there with different modifications like eVGA's ACS card, but generally all 7800GTX cards have similar cooling..
