Introduction

Although Xigmatek is a relatively new company, their cooling solutions and power supplies are well known amongst technology enthusiasts in Europe. Their products quickly earned the company a good reputation and they are now one of the favourite thermal solution manufacturers in Europe.

Today we will have a look at three of the most popular CPU coolers Xigmatek currently offer; the HDT-S1283, the HDT-RS1283 "Red Scorpion" and the HDT-S1284 "Achilles". All three of the coolers are based on the same design and Xigmatek's Heatpipe Direct Touch technology, but each one targets a different user group. We will thoroughly examine all three of them in this review.
