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 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.
