Like I mentioned above, the Gigabyte HD 2400 XT uses a unique cooling method called "Screen Cooling". This takes a fan-less heatsink and extends it past the width of the PCB, making the card essentially a full size ATX card. This gives the video card a wider and thicker look, while effectively cooling it with zero noise level, from the lack of fans. This design also protects the VGA connection, which uses a ribbon cable to extend the port on the PCI bracket, from snagging or damage. By removing the outer connection bracket we can get a better look at the fins of the heatsink and the holes which allow air flow from the case to pass through them and cool the card.
