I picked up a V7 and it works well. It's big and pretty, and it fits my other Tt cooling in my case. That's the main reason I went with it. It cools my CPU fine. I was running about 32.5C when I had first applied compound, but since then, the temps down here (South) have risen and my ambient went up a couple of degrees so I'm a degree or two up again.
Overall, it does what it's supposed to, but it's fairly noisy, so if you're going for ultra quiet, look at some other options. Let me say that a different way. You can tell the difference between stock AMD and Volcano 7.
For me, it's great, though. Looks good and cools fine with a tolerable level of noise. Oh yeah, and at $17, you don't have to fret your decision so much if you decide that you wanted the SK6.
SVC is a good company too. I bought my V7 from them about two months ago and they delivered a day early with very decent prices on shipping.
Hope this helps.
