Ninjalane has posted their review of the super silent i5 cooler from Thermaltake called the Silent 1156.

Our heatsink tests are designed to look at cooling capacity at two different heat levels. The difference between the two determines how well a cooler can handle the different heat loads. The ThermalTake Silent 1156 did an excellent job in our tests by easily outperforming the stock 1156 cooler and proving it could handle a minor overclock up to 3.2Ghz.
