Frequent Maximum PC readers will have noticed our love affair with Cooler Master’s Hyper 212 Plus CPU cooler. The 212 Plus came out of nowhere and captured our hearts—and a spot on our Best of the Best list—with its excellent cooling power and rock-bottom $30 price tag way back in 2009. It’s not the best CPU cooler we’ve tested, but we’ve installed it in virtually every stock-clocked PC we’ve built since, thanks to its unbeatable price/performance ratio. Cooler Master’s all-new Hyper 212 Evo costs five dollars more than the Plus. But is it five dollars better?
