On the review block today I've got the Kingwin Revolution RVT-9225 CPU Cooler, it utilizes what Kingwin calls H.D.T, or Heat Pipe-Direct Touch cooling technology. H.D.T is just a fancy term really, the cooler does not have a base as other coolers to, the heat pipes directly touch you CPU to provide maximum heat transfer efficiency. In my time with this cooler I tested in on both C2Q and C2Q processors and found that it performs very well, its performance rivals that of many of the top coolers on the market today.
