I'm planning to buy CM Hyper 612 CPU cooler for my i5 3570k, and I"m wondering If Hyper 612 will fit. Though the nzxt site says that only 160mm CPU coolers will fit(Hyper 612 is 163mm), I'm still hoping it would. Any thoughts about it? or any other recommendations that have the same price range w/ CM hyper 612? I'm on a tight budget and Im planning to OC to 4.5 ghz. any help would be appreciated!
