http://www.guru3d.com/article/corsai...cooler-review/If there's anything resourceful and plenty to be found of in the market, it has to be the sheer number of CPU coolers. Over the years CPU coolers have evolved in many ways and series. One of the more popular product developments that set a new trend were of course heatpipe based coolers. The market is completely saturated with the most exquisite models. Heatpipe coolers are good and silent, as such these are two of the most important features a cooler should have... good performance versus silence. The third factor is the same as always, pricing needs to be acceptable.
