The cooler was the Xigmatek Thor's Hammer. The Hammer is one of those coolers that when you first see it you could not but think how does this thing compete with the big boys like the Coolermaster V8 and Thermalright T.R.U.E. Well that is what I thought anyways. And to think about how well the HDT-S1283 has done at a budget price you would think this monster would be a Top Ten cooler killer. The Hammer is based on the Heat pipe Direct Touch, or HDT for short, technology. To explain this in a brief sentence, the heat pipes come in direct contact with the IHS of the processor for more direct cooling. We will get more into that later in the review. So, you have to read a little more to see what this cooler and HDT is all about.
