24.05.2013 - Reliable PC Reviews NF-A14 FLX
Test verdict: "Noctua’s NF-A14 FLX, NF-A14 ULN, and NF-A15 PWM are all excellent fans. They are virtually inaudible yet manage to retain excellent airflow and static pressure, and are backed by the reliability of the Noctua brand." (Mike Lewis, Reliable PC Reviews)

23.05.2013 - pc-overware.be NH-L9i
Test verdict: "Ce que nous pouvons dire c’est que ce petit Noctua sera le compagnon idéal des cartes mères mini-itx couplées à un processeur Intel à faible consommation et placées dans un boitier exigu. Il s’adressera aux perfectionnistes exigeants quant à la qualité des composants de leur système. Des systèmes Home Cinéma principalement, mais aussi un petit serveur ou un nettop." (Stéphane Halleux, pc-overware.be)

22.05.2013 - CoolingTechnique.com NH-U12S
Test verdict: "Le nuove soluzioni di raffreddamento a marchio Noctua si dimostrano più come un passo avanti nella tecnologia dell'air cooling piuttosto che come la solita minestrina riscaldata a cui ormai ci stanno abituando da qualche tempo a questa parte." (Damiano Villa, CoolingTechnique.com)
