This cooler, tailor-made for AMD processors with TR4/SP3 socket, uses automatic speed control and ingeniously designed fins. They direct the airflow in a particular way to ensure that cooling of the key components is as effective as possible. Unlike many other fans, the NOCTUA NH-U12S also features silicone pads that reduce vibrations. Both weight and operating noise are very low, the cooler weighs mere 870g (with fan) and the noise does not exceed 18.6dB after connecting the low-noise adaptor. Thus, on the acoustic scale, NOCTUA NH-U12S cooler is 11dB quieter than a whisper.
