NH-U12DO A3
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.
Performance optimised design
The NH-U12DO 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.
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-U12DO A3 supports Socket F as well as the newer G34 and C32 sockets.
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.
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!
2x NF-P12 120mm premium fan
Featuring advanced aerodynamic optimisations and Noctua's premium-grade SSO-bearing, the award-winning NF-P12 is renowned for its exceptional quietness and long-term stability. The dual fan configuration allows for increased performance and safeguarding against failure.
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.
