Noctua's DO line of coolers has become a default choice when it comes to quietly cooling AMD Opteron CPUs. Upgrading both compatibility and performance, the new A3 model features Noctua's professional NM-A3 SecuFirm2™ mounting system that not only supports socket G34, C32 and F, but also allows to install the cooler turned by 90°. Thanks to six heatpipes, a performance optimised fin stack and its two premium grade NF-P12 120mm fans, the NH-U12DO A3 cools even the hottest high-end Opteron processors at minimum noise levels. Bundled with Noctua's industrial-grade NT-H1 thermal compound, the NH-U12DO A3 forms a complete premium quality package for quietly cooling AMD workstations and servers.

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)
