"We've been busy in the Icrontic labs, and there is no shortage of heatsinks coming in. You can expect several new reviews in the not too distant future. We coincidentally received two very similar heatsinks from two different companies—Sunbeam's new "Core Contact Freezer" and OCZ's "Vendetta 2". Both are based on the popular "heatpipe direct touch" or "HDT" design. If you haven't already guessed, the heatpipes do not contact a base, but contact the heat source directly. It has proved to be an effective technology and more and more heatsinks are beginning to emerge with this type of design."
