I think we have a clear winner here, not in performance, but in quietness! The heatsink is just simply quiet in operation and it's much smaller in size when comparing to the Zalman and should fit in every AMD system out there. Installation was breeze and I do like the 3 grip clip because I don't have to worry that much as the cooler would not loosen easily. Nothing to complain here and the heatsink performed flawless. From my humble opinion, the cooler is just like a Pentium 4 cooler wannabe for it's large in size with a quiet fan solution! Of course, as usual, I would like to end here that the fan isn't really suitable for overclocking and thus, should be avoid at all cost if you are into overclocking!
