Fractal Design Dynamic X2 GP-14 Review

Dawfreak is back and after a long break we are looking into the recently
releasedDynamic X2 GP-14 from Fractal Design.

The concept of Fractal Design is to provide products with an extraordinary design level, without compromising the important factors of quality, functionality and pricing. The computer of today has come to play a central role in most people’s home, creating a demand for appealing design of the computer itself and its accessories. Our main product areas are computer enclosures, power supplies and related accessories
 All Fractal Design products have been thoroughly designed, tested and specified in our Swedish head quarter. The well-known ideas of Scandinavian design can be found through
all of our products; a minimalistic but yet striking design – less is more.

Dynamic X2 GP True all-purpose fans


The Dynamic x2 GP series comes in in two sizes GP-12 of 120mm and the one we are looking at today, GP-14 that is 140mm.

Key features

  • High grade LLS bearing with class leading 100,000 hours MTBF
  • Equipped with a counter-pull magnet that reduces the axial tension on the bearing
  • Fan geometry optimized for a good balance between static pressure and maximum airflow, resulting in good performance in all usage scenarios
  • Aerodynamically shaped stator struts including the wire strut. Helps reduce noise and unwanted turbulence
  • Stator struts sit on a wide angle to the trailing edge of the blades which result in a lower noise level and smoother noise profile
  • Strategically placed notches near the fan hub on the trailing edge of the blades further reducing the humming noise produced when the blades pass the stator struts
  • 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.
  • The customized design of the Dynamic Series fans contributes to a beautiful, cool build
  • Available in two color combinations
  • Available in 120mm and 140mm fan sizes


The Fractal Design X2 GP fans come in two color combinations, All Black
and Black frame white blades. The setup sent to me is the All black version.

Inside the box.

Inside the box we find the Fractal Design X2 GP-14 and the standard 4 set Fan screws, this is what you would expect for a fan with a price around $13.99179 kr.


Test system
Case: Fractal Design Define R5
CPU: I5 4690K
Motherboard: ASUS Z97-A
Ram: 16 gig Corsair PRO 1600mhz (CMY16GX3M2A1600C9R)
System hard drive: Samsung EVO 850
Interface: PreSonus Focusrite scarlett 2i2 Gen2
CPU Cooler: Noctua NH-U14S


For this review I have decided to install the three Dynamic X2 GP-14 in what i believe is the best setup for a Home-studio build, where Two fans are used as Intake and one as exhaust.
all fans are connected to the Fractal Design R5 fan controller.


The Concept and basics on how I test.
When it comes to testing Case fans for use in a studio environment I want to push the test rig so that i know that my system gets heat generated, and i like to do that with real world applications. but music production does only push the CPU so i don’t feel that would let me find the information i feel is relevant therefore my test are done with the use of my second hobby that is playing World Of Warcraft.

I start by setting the Fractal Design R5 fan controller to 5V and play for 30 min and take the maximum temps recorded with HW-monitor. this test is then also done with the Fractal Design R5 fan controller set to 7V and 12V.

Now my system is extremely quiet even when gaming so i can easily hear if the fans interfere with the quiet computing that i want for my Studio PC.
The comparison will be done against my current setup, That is three of the previous generation Dynamic Gp-14.


Test results

Fan Voltage Cpu Temps GPU Temps Fan Noise
GP-14 (R5) 5V 56c 66c Inaudible
GP-14 (R5) 7V 53c 61c Very small hum
GP-14 (R5) 12V 50c 58c Small hum
X2 GP-14 5V 54c 62c inaudible
X2 GP-14 7V 50c 59c inaudible
X2 GP-14 12V 47c 55c Very small hum

Since I have been using the Stock fans (first gen Dynamic GP-14 series) that came with the Fractal design Define R5 I had hopes on the X2 GP-14 and they sure are a step up Compared to the previous generation as they have a much lower noise output at 12V and the very small hum that can be picked up from the stock GP-14 is non existing on the X2 GP-14.
To also see a small temp drop specially on the GPU is a welcome bonus.

I decided to also try and find at what RPM the fans become audible, to do so I unplugged the Lower front intake fan, after that I connected the X2 GP-14 used for exhaust and the top X2 GP-14 as intake to the Asus z97-a fan connectors and used the Bios fan controller to individual increase the fan to a point where i could hear it.

The Intake fan was inaudible to 892 RPM before i start picking up a small hum.
The Exhaust fan was inaudible up to 806 RPM before i start picking up a small hum.
Note only one fan is running at the time, and the reason for the Exhaust becoming audible at lower RPM is probably due to the case Fan grill blocking the airflow.

So the testing of the new Fractal Design Dynamic X2 GP-14 has come to an end, and I could not be happier with the new generation of an already great fan.
Not only does the X2 GP-14 deliver Better cooling, it also has lower noise where the
X2 GP-14 is inaudible at 7v and has a very small hum at 12V
so if you are adding or changing fans to your PC I strongly recommend you to get the Fractal Design Dynamic X2 GP-14 as i am confident you will be satisfied.


  • Affordable
  • quiet
  • good cooling



  • None




I would like to thank Fractal Design for letting me do this review.
And as always to my readers… THANK YOU!!!
