Well, I recently built a computer with the Hyper 212+ and think it is an excellent cooler, especially for the price. I found it very easy to install (as long as you read the directions carefully and watch the installation videos on YouTube). It cools my i5 quite nicely while staying at low fan speeds (and thus silent). I am not sure how it compares to the Dark Knight, but in most comparisons I have seen it hangs with the best for much less. And I can also confirm the 212+ does come with a bracket for all of the recent AMD and Intel sockets/LGAs.
