CPU cooling system Noctua NH-U9S: review and testing

We’ve tested a lot of motherboards in format Mini-ITX, which are intended for the building of compact computers. Many of them in terms of overclocking are not inferior to their more dimensional counterparts, demonstrating the great overclocking potential. Therefore, when building computers there is a need in a compact and efficient cooler, which can cool an overclocked processor, fitting in with the small dimensions of the housing.

Although appropriate solutions are not too many, but they do exist. For testing we got cooler of compact height of only 125 mm. When meeting novelty on the official website you can learn about it a lot of interesting features: compatibility with most current connectors, excellent equipment, the use of high-quality PWM-controlled 92mm fan, an impressive warranty period of 6 years looks very tempting.

Noctua NH-U9S

However, our readers watching the Noctua products are used to see a vivid example of the painstaking detail of the Austrian approach to promoting the establishment of a number of effective and quality coolers. Therefore, we are interested to have the next to the representative of the company in our test lab. We are talking about CPU cooler Noctua NH-U9S.

Packaging and content

Noctua NH-U9S

Even a cursory look at the packaging of Noctua NH-U9S you can recognize "handwriting" of the producer. The first is, of course, the characteristic colors. But also the features of this product include excellent information content. Thus, the provided information may be described as exhaustive, and the only thing missing a "live" image of placed inside device.

So, the face has the specification of the manufacturer about a tower cooler that can boast the following advantages:

  • NF-A9 premium fan - a high-quality fan Noctua NF-A9 is used for active cooling;
  • Award-winning NH-U series - novelty belongs to a series of coolers Noctua NH-U, which in 2005 received more than 800 awards and recommendations from a variety of IT-editions;
  • 100% RAM-compatibility - full compatibility with memory modules of any height;
  • 100% compatibility with PCIe cards on Mini-ITX - the manufacturer guarantees that the new product will not block the slots for expansion cards;
  • PWM-support and Low-Noise Adaptor - support for function of speed control by PWM, as well as the presence of LNA-adapter to reduce noise;
  • SecuFirm2 mounting system - a proprietary mounting system SecuFirm2 provides excellent compatibility with a variety of motherboards, allowing you to install a novelty without difficulty;
  • Compatibility with past and future sockets - the aforementioned fastening system ensures compatibility with a number of obsolete, current and even future processor sockets (the latter refers to Intel LGA1151 CPUs Intel Skylake);
  • 6 years warranty – being confident in the quality of the products, the company Noctua provides for a novelty as much as 6-year warranty.

The reverse side presented in eight languages, informs us about the use of the cooler 5 heat pipes. Due to their asymmetrical placement, fan cooler has a square profile with dimensions of 95 x 95 mm, which gives it excellent compatibility with adjacent slots. Also, to increase productivity here is possible to install additional fans on the opposite side of the radiator. Also here is noted the presence of complete thermal paste Noctua NT-H1, which boasts of excellent thermal conductivity properties.

On the side of the box you can find a detailed description of the features of the cooler, and also to learn its characteristics and equipment.

Inside the box the cooler is securely by a cardboard damper. Packaging is hidden in a separate box where all components are in separate place.

Austrians characteristic attention to detail is very noticeable when you look at the package. It includes not only all the components, but also following additional features:

  • reinforcement plate for the platform Intel;
  • metal fittings for different platforms;
  • a set of racks, nuts and bolts;
  • two brackets for additional fan;
  • screwdriver;
  • thermal paste Noctua NT-H1 in the syringe;
  • adapter to reduce the speed of rotation (LNA);
  • metal logo of Noctua;
  • the installation guide of the product on different platforms (AMD, Intel LGA115x and LGA2011).

As you can see, it is quite difficult to reproach the manufacturer: the package contains a set of necessary, useful and just pleasant components, allowing the use of novelty as efficiently as possible.

Design and structure

Noctua NH-U9S

Radiator of cooler has a classic tower. It is based on 5 copper plated U-shaped pipes with a diameter of 6 mm, which penetrate 43 aluminum plates. The latter have a thickness of 0.45 mm and are spaced at 1.7 mm apart.

Three pipes are directed vertically, while the other two have a bend at the base. Through this approach, excellent compatibility with nearby slots is achieved.

Pipes are arranged to heat the largest possible area of the radiator. It is excellent approach, which we have already seen in the models Noctua NH-U14S and Noctua NH-U12S. Lets’ recall that two solutions showed excellent efficiency in cooling of the overclocked processors.

Heat pipes of radiator are neatly soldered to the base, which should be the best effect on the heat transfer.

Fixing part of the pressure plate has a cooler mounted by a single screw. Install and remove this element can be quite simple, using a complete screwdriver.

Base of the cooler has dimensions of 40 x 38 mm. It is made of copper. To prevent oxidation, it is covered with a layer of nickel, as well as heat pipes. The manufacturer took care about its polishing: the reflection is blurry, but no defects or grinding marks on the basis were noted.

Active movement of the air flow is assigned to a 92-mm fan Noctua NF-A9 PWM. It is based on self-stabilizing bearings of second-generation (SSO2), which provide an impressive MTBF about 150000 hours. Other advantage of Noctua includes the use of technology to optimize acoustic AAO (Advanced Acoustic Optimisation), which includes three components, positively affecting the noise level. Also interesting feature of this solution is meanthe technology Flow Acceleration Channels, which means the presence of specific channels that reduces the noise of the vortex air flow, and improves the efficiency of the fan. For more information about these features you can learn from the corresponding review.

Fan Noctua NF-A9 PWM boasts of low minimum speed (400 rpm) that will be pleased by lovers of silence in the system unit. The maximum values (1550 and 2000 rpm and witoput LNA, respectively) are chosen in such a way as to achieve a balance of comfort and good efficiency of the acoustic background. Thus, even the noise level of 22.8 dB at a maximum speed is hardly uncomfortable.

Propeller is powered by one 4-pin connector. The length of the wires from the fan is 20 cm, which is quite enough for its easy connection.
