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.

26.11.2014 - ZeDen.net NH-D15
Test verdict: "Au final, le bilan de ce ventirad est vraiment très bon. Les améliorations apportées par Noctua à son produit phare, le NH-D14, nous ont vraiment convaincues. Le NH-D15 est bel et bien le meilleur ventirad de la marque, notamment grâce à ses nouveaux ventilateurs et à son design de radiateur revu pour une meilleure comptabilité. Bien sûr, ce niveau de qualité a un prix, mais il ne faut pas oublier que si cette solution haut de gamme - modulaire et adaptables à presque tous les sockets - peut paraitre chère, elle peut rivaliser avec les watercooling AIO les plus récents !"
