NF-A4x20 PWM

It is clear as soon as you get your hands on the packaging that this latest line of Noctua cooling fans exude quality. For many people, the trademark colour scheme will always be a love/hate relationship but there's no denying that it has become synonymous with the Austrian manufacturers premium products. These new A-Series additions are no exception and shift decent volumes of air whilst performing very well acoustically. The fact that their quiet performance can be lowered even further using the supplied LNA (and ULNA in the case of the FLX NF-A12x15) is a bonus. We would imagine that the majority of buyers considering the slim 120mm model are going to be looking to implement one or two in an HTPC environment, or perhaps as a push/pull combination in a smaller form factor chassis. The 200mm NF-A20 is a little different in that it is arguably an even more niche model - in the age of downsizing how many people still own a case capable of housing such a hefty blower. On the other hand Noctua should be applauded for now offering their premium, and exceptionally quiet cooling solutions, in almost every conceivable frame size.
