Hi, while researching fans for my new build (i7 4790k, z97p-d3, 16gb ram, r7 260x if it's useful for anything), I came across the hyper 212 evo, and based on the high price to performance ratio, I decided it was the cooler I was after. Later I found that another variant of the evo is offered in the U.S. (I'm in the UK), with a faster but louder fan, and shipping looks difficult. Which one should i chose based on my build specs?
