Ideally every CPU cooler should perform well, which most do. But in the age of advertising and marketing, consumers are easily mislead into believing a product will perform well just because of the company branding it. I have reviewed some very nice coolers over the summer by some of the most well known names in the industry; only to be let down by their claims of premium performance. Well, to be honest, prior to very recently I had never heard of Xigmatek before. Just a few weeks ago Benchmark Reviews unveiled the Xigmatek HDT-S1283, which tested to be the best-performing CPU we have seen to date. Perhaps on the same level is the Xigmatek XP-S964 Copper Heatpipe CPU Cooler.
