Accuracy on tests like this is a tough call, however they certainly sounded like they were careful.
Anyway, good to be skeptical and ask for more sources. Here is Frosty Tech's review, probably the most respected in this business:http://www.frostytech.com/articleview.cfm?articleid=2419&page=1
Unfortunately they don't have a V10 I think. I couldn't really find another comprehensive review of it, but my guess is that it is good, but not $150 good. I do feel confident saying the Hyper 212+ is one of the best perf/$, due to its excellent performance and low $30 price tag.
