Normalized Noise Tests
For these tests, I set the fan to speeds with noise output at the following predefined levels: 20/25/30/35/40/45 dBA. I skip the corresponding tests if the fan under the test cannot reach some noise levels. The speeds shown in the graph below are measured with the fan in a clear space inside my hemi-anechoic chamber without any obstacles. I set these speeds on the Longwin machine, but they slightly change because of the variable conditions that the device applies.
Lately, we discovered a peculiarity of the Longwin apparatus, so we are re-testing every fan we have, and we will continue to double-check all results because it seems the Longwin’s fan controller doesn’t “like” speed control for these tests, but it works better with PWM control. This is why you will find differences with results listed in previous reviews; we constantly update the noise-normalized tests to make them as accurate as possible!
20 dBA Noise Output
This fan has a double ball bearing, which typically is noisier than sleeve/FDB/HDB/Rifle bearings, but as you can see, the fan has the highest speed at 20 dBA normalized noise, meaning that its design is highly noise optimized. The airflow is decent, and the static pressure reading is pretty high, losing only to the (way) more expensive Phanteks fan.
25 dBA Noise Output
Again, top speed, high airflow, and very high static pressure.
30 dBA Noise Output
Top speed, decent airflow, and high enough static pressure. In this noise level, the P12 Max dropped to third place from second place in static airflow.
35 dBA Noise Output
The same scenario, top speed, high enough airflow, and high static pressure. Nonetheless, the performance gap with the Phanteks T30-120 got larger.
40 dBA Noise Output
I am getting tired, but I will write it again: the fan’s speed is high! The airflow is also pretty high, and the same goes for airflow, which is very close to Phantek’s fan top performance! All these are at almost one-third of the price! The only problem is that power consumption is also increased.
