I am currently running a hyper 212 black edition as my cpu cooler. I want something larger so I can overclock my 3600, I have a Corsair spec delta that says it can fit 160mm cooler and my current cooler is 159mm. The cooler I'm considering though is the BeQuiet Dark Rock Pro 4 which is 163mm and I notice there a slight bit of room between the glass and top of the cooler. Wondering if the extra 4mm will stop this cooler.
