Noctua NH-U12DO A3 AMD Opteron CPU Cooler

Noctua's new AMD Opteron cooler has everything needed to cool any compatible CPU quietly.

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 you to install the cooler rotated by 90° from normal if required to avoid collision with motherboard components.

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.

Features

  1. Performance optimised design
  2. Can be turned by 90° for optimal compatibility and positioning
  3. Drop-in replacement for standard AMD coolers
  4. 2x NF-P12 120mm premium fan
  5. NT-H1 thermal compound
  6. Compatible with AMD G34, C32 and Socket F

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 now 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.

Noctua NH-U12DO A3 : first-rate cooler!

,

I bought two of these, for a dual-CPU build and they are very high quality CPU coolers.

While not exactly cheap (especially when buying two!), they were cheaper here at QuietPC than other "e-tailers" and I was happy to use QuietPC again because of their commitment to customer service and satisfaction.

Consistent with other Noctua products, they are very well made and easy to assemble and install.

I have no relationship with QuietPC, other than being a very happy, returning, customer.
