Tech-Reviews.co.uk has posted a review on the Xigamatek Red Scorpion S1283

Direct heat pipe technology on CPU coolers is becoming more frequent than ever, at Tech-Reviews we reviewed a Nexus HOC-9000 a few days ago which made use of this new technology. The results from the heatsink bundle were good, but nothing to shout about. Today we've got another entry to the 'direct heat pipe' family, the Xigmatek Red Scorpion S1283. Unlike the Nexus, the Red Scorpion hasn't been designed for silence in mind; instead, it's been designed for pure performance and efficiency. Well let's just see shall we.
