8balls Hardware have posted a review of the much vaunted Thermalright SK6 HSF. here's a snip:
"This cooler has been much talked about since its appearance on the overclocking scene not too long ago for its super high performance. Its array of slim and tall copper fins are the secret to its performance. As a wholly copper cooler, it comes with no fan at all. Actually, Thermalright sells them without any fan, so as to allow the end user to choose which fan to use with it. Some resellers sell them with fans, more often than not, the Delta."
