Noctua has added two CPU coolers to its award-winning NH-U series of quiet coolers, both of which are single tower coolers. The NH-U12S uses the NF-F12 120mm fan and the NH-U14S uses the NF-A15 140mm fan. These new coolers were designed with large memory modules in mind and have adequate room to accommodate large RAM coolers. Noctua CEO Mag. Roland Mossig said, "The original NH-U12 and NH-U9 were the first Noctua products we brought to the market and the NH-U series has been a cornerstone of our success ever since. Representing the next generation of this venerable legacy, the new NH-U12S and NH-U14S are the result of almost 10 years of continuous development and optimisation. Both models mark a significant improvement in performance, convenience and compatibility."
