This cooler, designed for AMD Ryzen processors with a TR4 / SP3 socket uses automatic speed control and sophisticated slats. It directs airflow so that the cooling of key components is as effective as possible. Unlike many other fans, the NOCTUA NH-U14S also has silicone legs, raising it above the surrounding surface to dampen out vibrations. The fan is light-weight (only 1030g) and it operates remarkably quietly - after attaching the low-noise adapter, it will not exceed 19.2dB. On the acoustic scale, the NOCTUA NH-U14S cooler is almost 10dB quieter than a whisper .
