That's quite a lot of air. It kind of looks like the 3DFX Cool. But if you compare these two things, you notice the massive size difference. To test if this device actually works I used a small thermal cable that came with my Abit BF6 motherboard. All this thing does, it take the current temperature of wherever you place it.
Lets take a look.
With a difference of only five degrees on the BX chip, it might not be worth your money, but you might want to keep in mind that the actual card cool sits a good 4-5 inches below the chips and a good 3 inches off to the side. Anyways here's what it did for my processor. Though 6.5 degrees may not seem like much, Overclockers need all the coolness then can get, especially when trying to reach that sweet spot of 1GHz. The card cooler sat about 1.5-2inches below the processor. Here's where the Card Cooler really shines.
