Toms Hardware did a test of 10 socket 1156 cpu coolers
There are plenty others out there - I'm sure - but here's a benchmarked comparison of the 10 listed above.
Conclusion Page said:.....Four coolers that stood out today for superiority in various areas are Noctua’s top-cooling NH-D14, Thermalright’s nearly-silent MUX-120, Cooler Master’s superb-value Hyper 212 Plus, and Scythe’s jack-of-all-trades Mugen-2 Rev. B. Yet the one we’d use and the one we’d recommend might be completely different parts.....
....Even though the cooler cost $10 more, it’s impossible to ignore the six degrees Celsius cooling advantage Scythe’s Mugen-2 Rev. B provided over Cooler Master’s low-cost Hyper 212 Plus. Our biggest reservation in recommending it universally to budget-oriented overclocking enthusiasts is that it’s the second-biggest sink in the comparison. Putting the fan on the front causes it to hang over the memory slots of most motherboards, discouraging builders who prefer high-profile memory cooling....

...The combination of pros and cons leave us with several recommendations, depending on intended use. While Noctua’s customers have probably already committed themselves to purchasing the best-performing CPU air cooler, we’d recommend the cheaper Mugen-2 Rev. B as a better value for nearly any configuration that has the necessary mounting space. Thermalright’s MUX-120, on the other hand, is the best performing solution for builds that have limited mounting space, while Cooler Master’s far cheaper Hyper 212 Plus is worth considering by anyone who requires a similar footprint but can’t live with Thermalright’s higher price....
