As you may have noticed, the design of the CF80A is different than your regular card cooler. Most card coolers would hang over all your cards, cooling them adequately. This model, however, is installed over a smaller number of cards, 1-3 at most. The result is that fewer cards are cooled more efficiently. This is great for people who are overclocking their video cards to the max limit... Let’s say you’ve got some RAM Sinks on your memory chips. If you use the CF80A, you’ll have scores of CFMs moving over them which will greatly improve your overclock, assuming that thermal issues are blocking you from reaching higher speeds. Also, with this unit you cool both the card’s front and back sides. This is very nice, considering that video cards get hot at some spots from the back, such as behind the GPU.
