Review of the CPU cooler Noctua NH-D9L, or the joy of mini-ITX-systems

In mid-November last year, the Austrian company Noctua announced just three compact new items for use in miniaturized systems, mini-ATX, ITX and mini-ITX. The trio is equipped with the same fan Noctua NF-A9 with PWM-control. In our opinion, the most interesting novelty is the model Noctua NH-D9L , representing a kind of mini-super-cooler – it has a classic design with a two-tower mounted between the fan section and can also be equipped with additional fans. Its something we learned today and test.

Noctua NH-D9L: Packaging equipment

Noctua company since its inception and release of the very first products with special care that the packaging, whether expensive or super-cooler very ordinary 80-mm fan. In this style of boxes has not changed for many years – they are easily recognizable due to the characteristic brown colors. Was no exception and the box in which comes Noctua NH-D9L.

Informativeness of such a package is maximized. Perhaps only the Japanese Scythe can compete with the Austrians in this regard, but Noctua leads more complete specifications. Thus, almost all of the cardboard box filled with useful information. We should also note the description of the cooler is shown in eight languages, including Russian.

So scrupulously coolers nobody packs, believe me. Therefore, the fact that the device will reach to a potential buyer intact, no doubt.Flawless and reliable packaging Noctua NH-D9L. In the Color box by inserting additional cardboard shell consisting of two covers and the inside “boxes”.

Accessories sealed in a separate flat box with compartments that also convenient for users.

The list of accessories has everything you need for installation and further operation of the cooler. Each set of components sealed in a personal bag, and instructions for different types of platforms are separate booklets clamshell signed by the chairman of the board of directors Noctua.

We add that, like all of the coolers, Noctua NH-D9L equipped with high-performance thermal compound Noctua NT-H1 .

Produced novelty in Taiwan. The recommended price is quite high in comparison with the coolers of the same class of other manufacturers – it is 57 US dollars, but Noctua never differed democratic prices, giving priority to the highest quality of its products. Note that in this price includes a six-year guarantee.

Noctua NH-D9L: Design Features

Noctua NH-D9L – very compact and neat two-tower design cooler. Its total height is 110 mm, and the width and thickness of 95 mm.Weighs 531 grams cooling system, of which 438 grams occur in the radiator.

Two-tower heatsink combined the two sections of aluminum plates pierced with four heatpipes 6 mm in diameter, which is inserted between the 92-mm fan.

Externally, the cooler resembles some cube with rotating blades inside. In general, the cooling system is made very high quality and we can say, meticulously. Parts fit together perfectly, all the places soldered mates and none of the plates do not hang out with heat pipes.

Nickel-plated heat pipes pass through the grooves in the copper base and penetrate the radiator sections evenly throughout their area.In each section of the radiator 35 aluminum plates of 0.4 mm thickness, placed on heat pipes with intercostal spacing of 1.7 mm. The area of the radiator is only 4000 cm 2. Due to the compactness of the radiator to turn technologies are simply nowhere, but its developers have made the ends of edges in most areas of the air flow to reduce tooth resistance to air flow and efficiency of the cooler at low speed fan.

Thus, we achieve the most uniform distribution of heat flow in the ribs.

The processing quality of the contact surface of the base is at a very high level – to the mirror image of our Smeshariki did not have quite a bit of polishing.

However, a much more valuable by the fact that the base only smooth – we managed to get probably the best and most uniform heat spreader processor prints on it all the time for testing cooling systems for a given configuration.

Note that the contact force and the staff of fastening the cooler is very high.

Noctua NH-D9L equipped with one fan Noctua NF-A9 PWM size of 92 × 92 × 25 mm. This is a standard model Noctua with characteristic light brown frame and seven-bladed propeller.

At the corners of the plastic frame put silicone tips that reduce the transmission of vibrations from the fan and reduce noise levels.

Speed ​​adjustment is performed by PWM in two ranges. When connected directly to the fan will change its speed from 400 to 2,000 (± 10%) / min, and using LNA-speed adapter fits within the range of from 400 to 1,500 (± 10%) / min. In the first case, the noise level can reach 22.8 dBA, while the second – only 16.3 dBA. Other features you can find in the table above.

At the heart of the fan is branded bearing SSO2 (Self-Stabilizing Oil-pressure) to the normative life 150,000 hours, or more than 17.1 years of continuous operation. It’s hard to imagine what the system can survive this fan. On its stator – a sticker with information about the model and the individual electrical characteristics.

According to these data Noctua NF-A9 PWM should consume no more than 1.2 W, and, according to the results of our measurements, the peak power consumption of the fan was only 0.89 watts. Kick-off voltage is 4.3 V. The fan is mounted on the radiator by wire staples. Since the section of the radiator Noctua NH-D9L symmetrical, if necessary, it can be installed just three 92-mm fan, but additional brackets not supplied.

Noctua NH-D9L: Compatibility and Installation

Thanks to a proprietary mounting system SecuFirm2 new Noctua NH-D9L can be installed on any modern platform. LGA775 it already is not, therefore, support this connector cooler is not endowed. The installation procedure is described in detail in the manual , and for our test platform with LGA2011 it is almost the same as that of other systems of cooling air.

First, in the opening of a steel mounting plate processor socket screwed BSP threaded studs.

Then these pins are mounted steel guide.

And after that the CPU heatsink is installed and evenly drawn spring-loaded screws. It remains only to hang the fan and connect the cable to the connector chetyrёhkontaktnomu on the motherboard.

It will not take more than two minutes.

The distance from the bottom plate radiator Noctua NH-D9L to the motherboard does not exceed 40 mm, and the fan hangs another 20 mm lower, but since the cooler is very compact, the noise memory modules or radiators on the power components, he will not.

Inside standard computer chassis Noctua NH-D9L looks minimalistic – in such modest size it should fit perfectly in form factor mini-ITX.
