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 optimized 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 optimized designThe 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 optimized fin stack and an enlarged contact surface suitable for socket G34 allow for further improved performance.
- Supports G34, C32 and Socket FThanks 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 positioningNoctua'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 coolersScrewing 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 fanFeaturing advanced aerodynamic optimizations 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 compoundNoctua'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.
