Page 3 - Performance Tests
To test the performance of both the Cooler Master Mobius 120P ARGB and Mobius 120, our testing method invented right here at APH Networks was used. Although this test may not be the most comprehensive of tests, the results are qualitatively displayed at a minimum cost by using a piece of tissue paper and tape. As shown in the above photos, a piece of tissue paper was attached on the top of a fan. The tissue paper should be able to naturally fall down and cover the air outlet side -- the side where the motor rack is located -- of the fan. The fan is placed on the edge of a table to prevent air from reflected off any other surface to not skew results. Once the fans were powered on, the airflow, airflow consistency, and the amount of static pressure can be evaluated by observing the behavior of the tissue paper.
Taking a look at the pictures of the Cooler Master Mobius 120P ARGB, the tissue was raised evenly on both sides of the fan, indicating how air is evenly distributed. Further away from the fan, you can see the consistency in airflow. The 2400 RPM speed was very noticeable when looking at the tissue. Comparing this with the regular Mobius 120, you can see how the fan is competing quite well. The tissue is also raised evenly on both sides while having a similar consistency in airflow, but the Mobius 120P ARGB does still outperform it. Both fans performed exceptionally well thanks to the high airflow and air pressure. Speaking towards the consistency, the tissue paper held in-place well with very little movement, indicating steady airflow passing out the exit side of both the Mobius 120P ARGB and Mobius 120.
Sounds is another important factor when testing fans, as we want a good balance between performance and noise. There are limitations, as sound can be quite subjective to both the listener and the environment of the fans. The noise levels of this fan were tested independently in a quiet room with all other noises from our system isolated to ensure we are testing the fan alone. We rate the perceived noise on a scale of 0 to 10, where 0 is silence and 10 is an explosion. For the Mobius 120P ARGB at maximum speed, I would rate this fan at about 3.5/10, while the Mobius 120 would sit comfortably at a 3.0/10. This makes sense, as the Mobius 120P ARGB clocks at a higher RPM, generating a greater amount of noise. With an RPM of 2400 and 2050 for the Mobius 120P ARGB and Mobius 120 respectively, these noise levels are completely acceptable for the performance specified and observed.
