OCC awards this cooler with a Gold award for its good performance, quiet operation and six year warranty. It's pretty large though, and the price tag is kinda high.
"The Noctua NH-C14 is a C shaped cooling solution that uses a total of six heat pipes to transfer the the thermal load from the nickel plated copper base plate up to the large aluminum fin array. In a direct comparison to the NH-C12P SE14, the NH-C14 is taller by 16mm at 130mm, wider without the NF-P14 fan by a total of 14mm and deeper by again 14mm without the fan. This added size increases the cooling capacity of the NH-C14 and also the weight by a total of 150g driving the weight of the cooler to 700g without the fans attached. Weight creeps up to 1000g with both fans installed. Part of this added weight comes in the form of a brace used to help support the aluminum fin array. The NH-C14 has several modes it can be used in to fit a variety of installation scenarios. Both fans can be used for the best cooling while the bottom fan can be removed to address clearance issues while the top fan can be removed to fit the cooler into a tight chassis."
