As the topic says which is better? I have an intel i5 2500k with an h67 motherboard. My stock cooler is giving some problem so thought of replacing it. Also 412 Slim is a bit costlier. What i'm thinking is that in the cheaper alternative i'll buy the Hyper 212 Evo which comes with a single fan and add an additional fan later so it can act as with PUSH-PULL configuration. Any Suggestions?
