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 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 optimized 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 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 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. |
