Introduction and First Impressions
The Scythe Ninja 4 (SCNJ-4000) is the latest model in the Ninja series, and an imposing air cooler with dimensions similar to Noctua's massive NH-D14. But there's more to the story than size, as this is engineered for silence above all else. Read on to see just how quiet it is, and of course how well it's able to cope with CPU loads.
"The Ninja 4 is the latest model in the Ninja CPU Cooler Series, developed for uncompromising performance. It features the new T-M.A.P.S technology, an optimized alignment of heatpipes, and the back-plate based Hyper Precision Mounting System (H.P.M.S) for firm mounting and easy installation procedure. These improvements and a special, adjustable Glide Stream 120mm PWM fan result in an increased cooling performance while reducing the weight compared to his predecessor. Also the design of the heat-sink allows fan mounting on all four sides. This enables the optimal integration of the Ninja 4 in the air flow of the pc-case and reduces turbulence and the emergence of hotspots."
The Ninja 4 is built around a very large, square heatsink, which allows the single 120 mm fan to be mounted on any side, and this PWM fan offers three speed settings to further control noise. And noise is really what the Ninja is all about, with some really low minimum speeds possible on what is a very quiet Scythe fan to begin with.
Will a single low-speed fan design affect the ability to keep a CPU cool under stress? Will the Ninja 4's fan spin up and become less quiet under full load? These questions will soon be answered.

Noctua has launched two new single-tower air coolers in the NH-U series. The new NH-U12S and NH-U14S slim tower coolers come in both 120mm and 140mm sizes respectively. The air coolers are slim-enough to be installed in most system configurations, even with tall RAM heat-spreaders in use.
The Noctua NH-U12S is an updated version of the company's NH-U12P-SE2 cooler. It features a 45mm thick tower heatsink paired with a 120mm NF-F12 fan.
On the other hand, the NH-U14S is Noctua's first air cooler sporting a 140mm fan. The cooler is 52mm thick, and is compatible with Intel's enthusiast LGA 2011/X79 platform. Further, it uses NF-A15 140mm fan that provides ample cooling power at lower RPMs (which means less noise, ideally).
Both the NH-U12S and NH-U14S air coolers include Noctua's SecureFirm 2 mounting system, NT-H1 thermal compound, and PWM-controlled fans. Users can also attach the low-noise adapter to reduce the maximum fan speed from 1500 to 1200 RPM should they value quiet operation over maximum performance. Noctua is supporting both air coolers with a 6 year manufacturer warranty.
Both the 120mm NH-U12S and 140mm NH-U14S will be "available shortly" according to Noctua. The NH-U12S has an MSRP of $64.90 USD (59.90 EUR), while the larger NH-U14S is priced at $79.90 USD (69.90 EUR). In all, they appear to be decent air cooling options, and Noctua has demonstrated quality support in the past (such as the free Haswell mounting kit upgrades for older HSFs). Personally, I'm interested to see how the 140mm unit performs.
