The Gigabyte GV-NX73G128D
While the ASUS Extreme N7300GS was almost a replica of the NVIDIA reference design, Gigabyte differentiated their card by using a different cooler design. In fact, they totally did away with the fan!
Yes, Gigabyte has given this card a totally silent cooling solution. Instead of the small cooler used in the NVIDIA reference design, Gigabyte used a large aluminium heatsink, with an orange shroud covering the top. As such, the card is a full-height card.

All four memory chips are placed at the end of the card, on both sides of the PCB. But the two front chips are covered by the large heatsink.
Interestingly, Gigabyte chose to use a different memory chip. Unlike the NVIDIA reference design and the ASUS Extreme N7300GS which used Infineon memory chips, Gigabyte used Hynix DDR2 memory chips on this card.

The top and bottom views of the card show you just how thin the cooler setup is. Gigabyte kept the cooler no thicker than the back panel plate. You can also see the sticker that proclaimed the uniqueness of the Gigabyte passive cooler.
