Following the analysis of details, we now move on to the test results. These demonstrate that Fractal Design’s Momentum fans truly deliver. Just how well is ultimately up to each of you to judge. One factor is the aerodynamic design of the fans, another is the overall airflow design of the case, and yet another is the specific components being cooled. What we can conclude, however, is that the Meshify 3 XL is suitable even for the most demanding builds.
Results: Lower noise level (39 dBA)
What about the system fans? We’re testing the Fractal Design North XL in two fan configurations. One is labeled “3+0” in the graphs, which is the default setup – all three included fans are in intake positions. No fan is placed in an exhaust slot (hence the “+0”). That’s the first of the two configurations. In the second, all fans are mounted as exhausts, thus labeled “0+3.” In this setup, there are no intake fans, but three exhaust fans pulling air out of the case – one in the rear and two in the top panel. That’s the limit with 140 mm fans; no more than two can fit in the top.
On vibrations: With intake fans, we registered some vibration at the top front area of the case, but again, not to a level that would cause a significant increase in secondary noise (e.g., rattling of a desk surface). Behind the front panel structure, vibration is already negligible, and relocating all fans to exhaust makes vibration virtually unnoticeable.
Why is there a missing value in the chart for a case? One possible reason is that the fans couldn’t be set to the required mode – either because the minimum RPM was too high or the maximum RPM was too low. Another reason could be that the available cooling performance was insufficient for one of the test components, which led to thermal throttling. Temperature values are always recorded (and compared) at comparable performance levels.
They’re built on an exceptionally efficient aerodynamic design, but come at a lower price point. Using more flexible blades reduces manufacturing costs, and the bearings in the Dynamic 3 fans are also “simpler” compared to the Momentum series. For the user, this doesn’t necessarily mean any major drawback—on the contrary, you can look forward to more pronounced lighting, enabled in part by a larger area of light‑conducting material.

Our database now includes one hundred fans—75 in the 120 mm format and 25 models with a physical size of 140 mm. In this article, we have compiled all data into unified charts. What was once separated for clarity is now brought together again, and the commentary will also include a… look ahead regarding fan testing. But we can already reveal that there is still a lot more to come. Read more “The end, or just the beginning? 100 fans in HWCooling tests”»
