Today we are taking a look at the Pure Rock 2 FX CPU cooler from the aptly-named and acoustics-focused Be Quiet! One of the companys latest CPU air coolers, the Pure Rock 2 FX is intended to compete in the packed mainstream cooler market as a competitively priced all-rounder. Always a careful balancing act for cooler vendors, the mainstream market lives up to its name by being where the bulk of sales are, but its also the most competitive segment of the market, with numerous competing vendors all chasing the same market with their own idea of what a well-balanced cooler should be. So a successful cooler needs to stand out from the crowd in some fashion – something thats no easy task when all of them are beholden to the same laws of physics.
