關於AMD-Opteron靜音散熱,DO系列的散熱器已為消費者首選。在相容性和效能同時升級,新款A3使用Noctua NM-A3 SecuFirm2™扣具,不僅能夠支援socket G34, socket C32 和socket F,而且還允許散熱器旋轉90度來安裝。由於6條熱導管及優化的散熱鰭片,加上兩顆高性能的NF-P12/120mm風扇,還有NT-H1頂級散熱膏,NH-U12DO A3已成為AMD Opteron平台高階工作站和伺服器靜音散熱的最佳選擇。

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° 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.
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.
