I'm thinking about buying a noctua nh-d14, but I'm wondering whether it's a waste of money. As of now I have a Hyper 212 evo from a previous build. Temps are more than reasonable both in idle and load (25-30 and 55). Reason for wanting to buy a noctua is because I want to overclock and I have read forums/reviews that the ivy-bridge cpus get a lot hotter than the previous like the sandy bridge. I just upgraded from an amd to intel build this week. Another thing is I don't want to move towards liquid cooling, so any suggestions besides the noctua, so please only suggest air cooling heatsinks.
