Case fans are often times one of the most important elements in a build. Most cases come with a variety of fans these days, but they aren’t necessarily the best for cooling, nor are they the quietest available either. Finding a quiet fan that has good cooling can be rather difficult. Many stock fans either move a lot of air and scream or move little to no air at all and are silent. Finding the right mix between the two is key in a quiet well cooled case. Fortunately, Kingwin has done some thinking and have a new design on the market. These 120mm case fans have a new mounting system that doesn't require any screws or tools. Rubber nubs are all that hold these fans in place so it will be interesting to see how it all works out. Today we look at a pair of the Duro Bearing Silent Series 120mm case fans from Kingwin.
