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
It has decent airflow, but the static pressure is not that high.
25 dBA Noise Output
The airflow is high enough, but static pressure is close to the bottom of the chart.
30 dBA Noise Output
Airflow is close to 70 CFM, so it is high enough, but the static pressure is away from 2mmAq, so it is not that competitive.
35 dBA Noise Output
It starts to show its teeth at high speeds at airflow, but the static pressure cannot keep up with the SilverStone Shark Force 140.
So basically they lost in what was meant to be their niche of static pressure across the board to a cheaper rgb fan? 😂. Even more embarrassing is in Australia where these are about $65 aud where the shark’s have dropped to $25. Either way ur testing is invaluable for these more niche products especially, cheers.
Hi!
Thanks for the very cool and high-quality reviews, no one else does that.
I want to ask you to test noctua nf-a14, a new generation model will be released in the 2024q1, it would be cool to compare
Once it is out, I will definitely test it!
