Hello, Noctua NH-U12S. Meet AMD Threadripper. Traditional Noctua design and the world-class cooling ability of the NH-U12S is now available for Threadripper, and the result is marvelous, just as we expected. The slim design cooling tower sparkles with its five, polished nickel heatpipes tower while barely uttering a whisper with its NF-F12 PWM (pulse width modulation, for controlling fans) 120mm fan while providing great thermal cooling to AMD’s flagship CPU line.
