Part of their conclusion:
In a CPU cooling market increasingly dominated by AIO units it's nice to get your hands on a well-made traditional tower Cooler. It's also fair to say that thanks to easy assembly and quality components we had a very nice time indeed testing and reviewing the Cooler Master Hyper 612 v2. At just a smidge under £40 the 612 v2 is certainly one of the more affordable quality coolers on the market. Sure you can buy some others cheaper, but we really wouldn't recommend that you do as you're getting well into pot luck territory with regards to build quality and performance.
Given the performance this could easily become the king of Price Vs Performance for builders.
