I like the specs and the test results on this HSF but am concerned about its weight. At almost 1 1/2 lbs it far exceeds the limit established by AMD. I am also concerned about the mounting system being just a clip. The Swiftech MC462 is almost the same weight but it uses 4 screws than just a clip. I am concerned that this type of weight may crack the CPU socket tangs. Are my concerns justified or I am just being paranoid? Any words of wisdom?
