MadShrimps posted a review on the Noctua NH-U12S and NH-U14S CPU Cooler
A quote from the article:
Austrian Cooler giant Noctua released a while back two new additions to their popular CPU cooling line-up. Two single slim design tower coolers in two different versions: the NH-U12S utilizing a 120mm fan and it's bigger brother the NH-U14S, sporting a bigger 140mm fan. Both coolers are designed for uncompromising performance, however not at the cost of mainboard and RAM compatibility. Unlike other cooler manufacturers Noctua isn't updating it's product range on the fly, a clear sign that the design and technology behind their products is reflected in great lasting performance and reliability. The latter statement is backed up by a 6 year warranty on the cooler and included Fan.Noctua NH-U12S and NH-U14S CPU Cooler Review @ Madshrimps
