Noctua - Bild

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-B9 92mm fans, the compact NH-U9DO A3 cools Opteron processors up to a thermal design power (TDP) of 115W at minimum noise levels. Bundled with Noctua's industrial-grade NT-H1 thermal compound and fitting standard 4U chassis, the NH-U9DO A3 forms a complete premium quality package for quietly cooling AMD workstations and servers.

Caution: Due to its more compact design and quiet operation, the NH-U9DO A3 is approved only for processors with up to 115W thermal design power (TDP). Using the NH-U9DO A3 on higher TDP processors may be possible with increased case ventilation depending on the specific configuration but is not officially supported by Noctua.

    29.01.2015 - Syndrome-OC.net NF-F12 industrialPPC-2000 PWM
    Test verdict: "Noctua nous fait part de deux gamme bien distinctes et qui ont deux publics différents. En effet, la gamme Redux se veut plus grand public avec des vitesses de fonctionnement plus bas et des bruits également plus bas. De son côté, la gamme iPPC se veut plus orientée industrie grâce à la présence de la norme IP 52. Les deux gammes proposent des performances de ce nom tout en étant performantes a des prix plutôt attractifs. La gestion PWM est également un plus pour ceux voulant un bruit faible provenant de sa tour." (Batiste Hocq, Syndrome-OC.net)

    Test verdict: "Noctua has raised the bar once more for high end air cooling products: the NH-D15 is without a doubt a stellar performer, in combination with the two included brilliant 140mm PWM fans it still keeps noise level reduced to a minimum. Even when running the D15 with a single centered fan the cooling performance is more than adequate to cool down your overclocked processors. Noctua has provided every accessory you need with this NH-D15, from the big thermal paste syringe to the Low Noise Adapters, everything you will need is included." (Albrecht Mesotten, Madshrimps.be)
