Nanoxia FX12, FX+12
The next four fans come from the German Nanoxia Company that is a sub-division of the large Xen Micro GMBH. All fans ship in identically designed plastic boxes. You can see the fan inside through transparent front of the box:
There is a lot of information on the package starting with the list of key fan features and finishing with their detailed specifications. FX+12 models differ from FX12 by PWM support and corresponding rotation speed control function. Therefore, only the rotation speed regulator is different:
Besides the regulator, these fans are also bundled with four silicone mounts. They are of similar acid-green color like the ones from GELID. These fans are made in China.
At first glance, it seems that Nanoxia fans are very similar to GELID Wing fans: fan blades, frame and even 500 mm braided cable are of the same color and look alike. However, if you take a closer look at them, you will notice that FX(+)12 has seven blades instead of nice and they don’t have the winglets on their tips:
In fact, Nanoxia FX(+)12 fans do not have any distinguishing features (except for the unique color), so let’s check out what the manufacturer has to say about them. It turns out that the fan blades are made from high-tech Makrolon polycarbonate – very durable, water-resistant and capable of working in wide temperature range for a long period of time. That’s pretty much all they have to say about the peculiarities of the fans design :)
The fans measure 120x120x25 mm. Their weight is not specified. Each fan has 7 blades and a 40 mm rotor:
Speaking of the fans specifications we have to point out that there are two models within each fan type: one with 380-1250 RPM rotation speed, and another with 600-2000 RPM rotation speed. Maximum airflow for the first model is claimed to be 47.39 CFM and for the second – 79.14 CFM, their noise levels – 12-17 dBA and 17-33 dBA, and their static pressure – 1.11 and 1.57 mmH2O respectively.
As I have already said, it is hard to find anything unique about the fan blades:
Nanoxia FX(+)12 fans use ball bearings made using nanotechnology and minimum of abrasive materials. Due to special bearings design, the fans are water- and dust-resistant and should last up to 150,000 hours (at 25 °C). Very impressive number, I should say. And there is no reason for us not to trust the manufacturer on this one, as they provide their solutions with a 10-year warranty! The manufacturer claims that all Nanoxia fans are balanced manually, however, we didn’t see any traces of this on the fan blades.
As for power consumption, Nanoxia also did a great job here. Besides low startup voltage of 4 V, the fans consume comparatively little power. For solutions with 1250 RPM maximum rotation speed the current is at 0.1 A and maximum power consumption shouldn’t exceed 0.6W. As for the solutions with 2000 RPM maximum rotation speed, these parameters equal to 0.28 A and 1.92 W respectively. They owe this low power consumption to the ECO-motor that was developed together with X-Spice Technology Co. Ltd. Of course, all these technologies and high-end materials affected the price of the fans. The 1250 RPM model sells for $16, and the 2000 RPM model – for $19.
Let’s take a look at the obtained test results for the Nanoxia FX(+)12 fans:
The junior Nanoxia fan lost to the previous two GELID fan models in airflow readings, while the higher-end fan turned out significantly ahead of them. Nevertheless, the results of Nanoxia fans airflow measurements fall into the middle category. However, when it comes to noise levels, both Nanoxia fan models look way better than GELID solutions (certainly, the top one only up until ~1500 RPM). Nanoxia FX12-2000 fan is one of the airflow leaders of our today’s test session. We didn’t notice any parasitic sounds during work: nano-bearings and fan motor deserve a good B+ here. We reach acoustic comfort zone at 900-930 RPM. As for the power consumption, Nanoxia doesn’t have anything to boast here, because the results we obtained in our lab are almost twice as high as what the manufacturer claimed (the results demonstrated by PWM models are identical to those by regular FX12 fans. The startup voltages are 3.6 V for the FX12-1250 fan and 2.1 V for FX12-2000 fan.
