Hmm. I did the research, and I came to the conclusion that this was a very good deal. Very much bangs for buck..... But: (And I am sorry, because I really wanted to love it).. a) One of the screws was cross-threaded, and could not be used. I had to either bodge or return it. (I bodged; luckily, a friend was nearby with a nearly same-size screw.) b) On an AMD CPU this cooler can ONLY drive upwards, ie towards the top of the case. As I say, I did some research, and there is nowhere saying this. (and I wanted to love it) c) Having fitted it, I can't put the side of my case on. And my case is not tiny. In all; a reluctant 2/10. (It seems to be cooling reasonably well). ps it is acceptably quiet, and it works.
