There are many ways to design a good air powered CPU cooler, but just as many ways to affect the performance. Does the size of the fan matter as much as the size of the cooler? Does the flowing copper fins of something like a Thermaltake V1 CPU cooler ensure it'll cool better? Though Cooler Master's new Hyper N620 CPU cooler doesn't look like a great big copper flower, it does have a lot of fins and a couple of big fans.
