I'm looking specifically for a big massive benchmark of as many high-end 1156 coolers as possible. All the "good" ones at frostytech are obsolete, not 1156, or OOS.
What about some recent reviews, like over at Hard or something
The others have given good advice. I'd add some but the most recent sets of reviews I have found have been on 1366. If you find any good reviews of coolers using 1156, let us know.
