CPU Cooler NOCTUA NH-U12S SE-AM4:The NH-U series is popular for a sleek, high-performance cooling system. Thanks to these features, many baseplates will not interfere with memory modules that are close and have a high radiator profile. It has an advanced rib and fan design with automatic speed control for even greater efficiency. As the name suggests, this model is ready for a new AM4 socket for AMD Ryzen processor.Key featuresEdition for the latest AMD Ryzen (AM4)HeatPipe heat transferEffective and silent premium fanAutomatic speed controlAdaptor for permanent reduction of speedFor cutting-edge hardware and clockingThe radiator has copper HeatPipe tubes  which quickly remove heat from the copper base into a passive cooler where cooling is quickly effected by the fan. The low-level noise contributes to the innovative self-stabilising oil bearing. Also, the air flow rate of 93.4 m3/ha with stamina of over 150,000h are excellent parameters for such a system. Using the LNA (Low-Noise-Adaptor) adaptor can reduce noise and fan speed. The package includes a very efficient NT-H1 heat transfer paste.
