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.



NH-U9P Performance optimised design
The NH-U9DO A3 is based on Noctua's much acclaimed NH-U series which have received more than 300 awards and recommendations from the international press. Six heatpipes, a performance optimised fin stack and an enlarged contact surface suitable for socket G34 allow for further improved performance.

SecuFirm Supports G34, C32 and Socket F
Thanks to the new NM-A3 SecuFirm2™ mounting system that includes brackets with both 3.5" and 4.1" hole spacing, the NH-U9DO A3 supports Socket F as well as the newer G34 and C32 sockets.

Kit Can be turned by 90° for optimal compatibility and positioning
Noctua's NM-A3 SecuFirm2™ mounting system makes it possible to install the cooler rotated by 90° in order to allow for an optimal positioning of the cooler and to evade compatibility issues on dual socket mainboards.

Kit Drop-in replacement for standard AMD coolers
Screwing directly to the standard AMD backplate, the NM-A3 SecuFirm2™ mounting system makes the new A3 revision a true drop-in replacement. Choose the appropriate mounting brackets, fix the two spring screws and you're done!

NF-B9 2x NF-B9 92mm premium fan
Featuring advanced aerodynamic optimisations and Noctua's premium-grade SSO-bearing, the award-winning NF-B9 is renowned for its exceptional quietness and long-term stability. The dual fan configuration allows for increased performance and safeguarding against failure.

NT-H1 NT-H1 thermal compound
Noctua's much-acclaimed NT-H1 is a well proven pro-grade TIM solution that provides minimum thermal resistance, excellent ease-of-use and outstanding reliability, which makes it suitable for use in professional server and workstation environments.

Test verdict: "المشتت NH-U12S من شركة نوكتشوا Noctua ربما لا يُعد أفضل الخيارات في فئته السعرية من حيث الأداء إلا أنه الأفضل من حيث هدوء الصوت، ولكن يُنصح بهذا المشتت لمن يستعمل معالجات Haswell أو Ivy/Sandy Bridge وبالتأكيد معالجات AMD الأقل من 125W ف استهلاك الطاقة لأفضل أداء ممكن مع صوت هادئ للغاية، فنعم لازالت مشتتات نوكتشوا لفئة مُعينة من المستخدمين الذين يودون الصوت المنخفض للغاية مع مشتت هوائي جيد، ولذلك فالمشتت يستحق أن تستبدل مشتتك الاعتيادي أو الاحترافي إن كان أقل ف الأداء أو كان صوته لا يُحتمل."

Test verdict: "Mit dem NH-D15 hat Noctua einen neuen Kühler in sein Sortiment aufgenommen, welcher sich nicht nur durch seine Kühlleistung an Overclocker und Enthusiasten richtet, sondern auch durch seine Laufruhe, welche gerade über die PWM Steuerung dank der sehr guten Kühlleistung erzieht werden kann auch für Silentliebhaber das Maß aller Dinge darstellt."
