As we mentioned earlier on, most manufacturers use the ATI reference design. One can only differentiate the cards from different manufacturers by the labels on it.

Hot air from the graphics card is exhausted towards the back of the card. The downside is that the exhausted air gets circulated around the casing as you cannot get the hot air exhausted out of the case. Dual-slot solutions are better in this aspect, but of course, you lose the use of the neighbouring card slot.
