To sum up our testing, we see that while the CCK-6027D HSF doesn't beat out it's larger and louder brother, it does manage to maintain some very acceptable cooling. With my voltage levels set as they are, the 73.6 watts of heat that my processor produces at 1333MHz is more than is produced by a stock 1.4GHz processor at standard voltage settings. What this amounts to is a cooler that will give adequate cooling to a system while being much quieter to the ear. And this is a trait that a LOT of people have been asking for.
Considering the qualities that Vantec was searching for, I'd say that they came very close to hitting it dead-on. About the only complaint I can point out with this cooler is the clipping mechanism. The small bar that secures the copper base to the fins sticks up just enough that it can be a bear to install the rear clip over the lug. Once it is on, the rest of the installation was a breeze, but that initial lug was a bit tough. Other than that, we have a very good cooler that produces reasonable cooling, and is easy on the ears.
Bottom line...This heatsink is not made for those who are very aggressive in their overclocking. It is, however, designed to work with fast processors in which noise levels are a concern. For these applications, this is probably the best low-noise sink that I've tested to date. Take a serious look at it if this is a concern of yours.
