Fractal Design Dynamic X2 GP12 and X2 GP14 – Test and Review

In the past months I’ve had the chance to test and review almost all of the fans from the tree different fan series part of the company portfolio. I saw pretty nice quality, features and test results and for that reason I am pretty excited to check what the latest arrivals in the Dynamic series, X2 GP12 and X2 GP14, have to offer.

For this test and review I received the new Dynamic X2 GP12 and X2 GP14 fans, provided to me inside carton packages with the same dimensions and structure but with different black and green colour scheme. On the front panel of the boxes there is a picture of the fan inside, accompanied by some basic details regarding the rated revolutions per minute, the company logo and last but not least the model name.

Of course, the full technical specifications, additional pictures of the fans and some of the basic features related with these products are located on the back side of the black/green carton boxes.

Enough about the packages, so let’s put them aside and proceed with checking the fan structure.

 

Fractal Design Dynamic X2 GP12 and X2 GP14 STRUCTURE

As soon as I laid my hands on the fans, I saw that they are in the typical Fractal Design signature, which features black and white color scheme and also the models are available entirely in black with black frames and propellers. The two samples which I got are with almost identical structure and the only difference is the physical dimensions and of course the delivered corresponding cooling performance.

So, let’s check the fan structure and features, which according to Fractal Design are with optimized geometry for a good balance between static pressure and maximum airflow levels, resulting in good performance in all usage scenarios making the fans true all-purpose models.

Both of the fans are manufactured with very solid entirely in black matte plastic square frames with physical dimensions of 120 x 120 x 25 mm for the Dynamic X2 GP12 model and 140 x 140 x 25mm for the Dynamic X2 GP14 model.

The frames themselves are not equipped with any vibration dampening materials and offer 4 mounting holes on each side to be used when installing the fans using the provided in the package screws or rubber dampers on a 120mm (105 x 105mm screw hole pattern) or 140mm (125 x 125mm screw hole pattern) case fan slots or on a CPU cooler heat sink.

Since the fans are part of the Dynamic series their frames are equipped with aerodynamically shaped thin stator struts, angled perpendicular to the trailing edge of the blades which results in an overall lower noise level and smoother noise profile.

Enough about the frames and by mentioning the blades, both GP12 and GP14 are designed with almost the same entirely in white propellers which offer 7 pretty wide and not very sharply angled blades. Both of the fans are equipped with propellers designed with strategically placed notches near the fan stator on the trailing edge of the blades for further reducing and diffusing humming noise produced when the blades pass the stator struts. And to further improve the efficiency and quiet operation of the fans the propellers include a “trip wire” on the rear side of the blades, near the leading edge. The trip wire introduces a larger turbulent boundary layer at an earlier stage, this delays the layer separation and improves both airflow and noise characteristics

Of course, to perform their duties the fans are equipped with the latest LLS bearing equipped with additional counter-pull magnet that reduces the axial tension on the bearing and significantly increases the life span of the products, which with this motor are able to reach up to 100,000 hours of operation. Both of the fans are powered and regulated by 500mm long black ribbon cable and 3 pin connector.

With this motor installed the fans are able to achieve:

  • X2 GP12 is designed to operate at maximum 1200 revolutions per minute, delivering airflow level of 52.3 CFM, static pressure level of 0.88 mm H2O at noise level of 19.4dBA.
  • Xp GP14 is manufactured to operate at maximum 1000 revolutions per minute, providing airflow level of 68.4 CFM, static pressure level of 0.71 mm H2O at noise level of 18.9dBA.

 

Lets proceed the article with checking the additional accessories provided with the fans.

Of course by being part of the Dynamic series, both fans arrived with absolutely identical accessories pack which typically includes only one set of 4 metal black installation screws to attach the fans to the case fan slot.

Since I am done with checking the fans I believe it is time to check their actual performance.

 

Fractal Design Dynamic X2 GP12 and X2 GP14 TESTS

The tests will be conducted in my standard way. I will install the fans and test them at 5V/7V/9V/12V and my goal will be to check the performance of the products in real conditions. They will be tested under close-to-perfect conditions, not taking into account any external factors. The results achieved during the test can in no way be the same if the models are mounted on a cooler or on the case fan slot of any modern computer case. I will measure the amount of air going through the fans for one hour and their speed. For this I use a fan controller, a voltage meter, an anemometer and a stand made specifically for this purpose.

And this is what the fans look like installed on my test stand:

The test results are shown in the following charts:

The anemometer showed the following air speed passing through the propellers:

After mounting the fans onto the stand, and leaving them to rotate for about 60 minutes at maximum speed, it was time for the tests to begin.

As with my other tests, again I started with a gradual increase of the voltage through the Lamptron FCT starting at 0V and X2 GP12 made at least one revolution per minute at about 4.5V, while X2 GP14 started rotating at 4V. To perform all of the tests I had to increase the operational voltage to 5V.

Test at 5V:

At the first test, conducted at exactly 5V , X2 GP12 was rotating at stable 690 revolutions per minute, providing airflow level of 41.28 cubic metres per hour, while X2 GP14 was providing airflow level of 35.04 cubic metres per hour at only 510 revolutions per minute. At this test both of the fans were absolutely quiet.

Test at 7V:

At the second test, performed at 7V, X2 GP12 was rotating at 900 revolutions per minute, providing airflow level of 55.68 cubic metres per hour, while the big model was rotating at 660 revolutions per minute with airflow level of 52.08 cubic metres per hour. Again, both of the fans remained dead quiet.

Test at 9V:

At the third test conducted at 9V sharp, X2 GP12 was providing airflow level of 70.08 cubic metres per hour while rotating at 1125 revolutions per minute, while for the X2 GP14 the airflow level was 68.84 cubic metres per hour, while rotating at 825 revolutions per minute. At the third test both of the fans were still quiet.

Test at 12V:

At the last test conducted at 12V, both fans delivered their maximum performance, which for the smaller model was airflow level of 84.48 cubic metres per hour at 1440 revolutions per minute, while for X2 GP14 it was 86.64 cubic metres per hour, while rotating at 990 revolutions per minute. At this test, X2 GP12 started generating a noise coming out of the air passing through the propeller, while X2 GP14 remained quiet.

 

Fractal Design Dynamic X2 GP12 and X2 GP14 CONCLUSIONS

1. Fractal Design Dynamic X2 GP12 and X2 GP14 Performance:

By being part of the Dynamic series, Fractal Design X2 GP12 and GP14 fans are entirely made to cover high standards and to be an ideal solution for any usage scenario and further more to be even better than their ancestors.

The major difference, which I was able to notice through the review, is the renewed LLS bearing, which is capable to significantly improve the overall life span of up to 100 000 operational hours and at the same time provide the same or slightly better airflow and static pressure levels, while maintain the same or lower noise level.

Through the tests both of the fans provided stable and reliable airflow levels, which made me think that they are capable to work as cooling units installed on CPU heat sinks with higher fins gap compatible with 120mm or 140mm fans and keep low or middle grade processors running cool and stable at default or just a little bit overclocked frequencies.  For high or extreme overclock more powerful fans will definitely be required since the static pressure level of these models is also average.

Regarding the noise level, X2 GP14 was dead quiet through all of the tests, while X2 GP12 was absolutely quiet through the first 3 tests and started generating a tiny noise coming out of the air passing through the blades at full speed.

According to my experience with the latest X2 G12 and X2 G14 arrivals in the series I should say that they are definitely worthy successors of the older GP12 and GP14 fans.

2.  Fractal Design Dynamic X2 GP12 and X2 GP14  Appearance:

There is nothing really much to say. Here again we have the standard Fractal Design signature black and white color scheme, which adds a stylish presence and which will definitely be a great addition to cases or modding projects in black and white.

I think both Fractal Design Dynamic X2 GP12 and X2 GP14 models deserve the following award:
