I can't blame the author for not doing a real test of this cooler.
no one does real cpu cooler tests ANYWHERE. if these websites really wanted to test a cpu cooler they'd be using an AMD FX 9xxxx series clocked up to 5ghz, and maybe overclocked beyond. The fact of the matter is almost every cpu cooler review fails to actually challenge the cooler they're testing resulting in a lot of weird or inconsistent results which are largely affected by ambient room temps.
It's why no one who's actually overclocked an AMD cpu will seriously consider ANY air tower for the task. Even though according to most CPU cooler reviews a number of air towers are "just as good" as closed loop coolers (of course they're testing them on 95W intel cpus with mild overclocks). It's why no one who actually seriously overclocks their intel extreme edition chips will ever consider an air tower, or if they're really serious about it, a closed loop cooler.
when you have every cooler performing just about the same in a review i'd say you have a cpu which is NO WHERE NEAR hot enough to stress any of those cpu coolers, and you need to look at more aggressive clocks or a hotter chip.
