Results: Static pressure, efficiency depending on orientation
With the FT12 fans, DeepCool has departed somewhat from the aerodynamic design of the older FK120 models, which is also reflected in their different functioning. In some ways it’s a change for the better, in some ways for the worse, but overall the fans are attractive. One of the reasons is the unconventional design, which allows you to see inside the motor. The housing is in fact clear and you can also light up underneath.
Results: Static pressure, efficiency depending on orientation
Explanatory note: Depending on the impeller orientation, different static pressures may be achieved. Within these graphs we observe the ratio between the “pull” and “push” positions, this gives us a sort of coefficient. If its value is above 1.00, it means that the fan exerts a higher static pressure when pulling. If the value is below 1.00, the opposite is true. Sometimes, however, this ratio is overall balanced.

- Evaluation
The results seem to indicate that this fan is optimized for RPM-normalized performance instead of noise-normalized performance, and little attention being paid to its behaviour on obstacles. Surprisingly disappointing to me especially vs. the excellent FT14.
In addition to facing significantly less competition, the FT14 has a narrower blade inclination. It’s significantly larger on the FT12 and although the frontal profile of the fan looks great, even for use on obstacles, it does have some weaknesses. Similar in nature to Arctic’s F fans, for example, although in the case of the FT12 they don’t manifest themselves as noticeably. With fans, an overall aerodynamic design is significantly more efficient for all scenarios. 🙂
