Features    [ Edit | History ]

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¡ã. 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.

NH-U12P 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.

¡¡
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-U12DO A3 supports Socket F as well as the newer G34 and C32 sockets.

¡¡
Kit Can be turned by 90¡ã for optimal compatibility and positioning
Noctua's NM-A3 SecuFirm2™ mounting system makes it possible to install the cooler rotated by 90¡ã 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-P12 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 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.

Pros
It's a Noctua.
Excellent cooling.
Quiet fan(s).
Cons
The four bracket screws are terrible to get in.
Summary
I bought this to go along with a socket G34 AMD Opteron 6376 16-Core server processor for a highly threaded workstation.

I'm not a newbie at assembling computers. The holes in one of the angled fastening brackets were spaced just a bit too tight making it almost impossible to get the second screw started. This cooler is massive with a huge base (seriously!), so they only give about 1 cm of spacing between the base and fins to try to get these brackets attached - and a 90 degree hex wrench to do it with.

Anyway... once I got it all assembled and stopped cursing, I spread a very thin coat of compound on the massive G34 processor, and mounted the cooler.

This Noctua cooler does a phenomenal job at cooling the processor even with all 16 cores at 100%. At first I couldn't believe the reported temps, so I had to touch the top of the base to see for myself just how cool this thing runs the Opteron.

Most of my systems run with Noctua coolers, and this is the reason why.
