The cheapest 140mm fan we’ve tested so far beats even significantly more expensive 120mm models at comparable noise levels. That’s because of the use of a larger cross-sectional area, as well as the efficient impeller geometry that the Stratus 140 PWM definitely has. “Cheap” fan doesn’t necessarily mean “weak”, though of course there are some compromises based on more limited manufacturing resources than with more expensive fans.
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.
stratus 14 is more expensive than arctic p14, therefore it’s not cheap.
It may or may not be. It will depend on the specific store you are shopping at. Somewhere the Stratus 140 PWM fan may be more expensive (probably especially in the US?), somewhere else it may be a bit cheaper.
