Results: Static pressure, efficiency by orientation
Why spend as much money on one fan as you would on four or five Endorfy Stratus 120 PWMs? There is a clear answer to this, but it may not be interesting to everyone. Especially when the fans are meant to fit well into builds designed with the best possible price/performance ratio in mind. That’s when low-cost fans make sense, and the end-user often dismisses the “imperfections” of the Stratus 120 (PWM) with a wave of the hand.
Results: Static pressure, efficiency by 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.
