Output Noise
I use a Class 1 Bruel & Kjaer 2270 G4 sound analyzer equipped with a Type 4955a microphone with a dBA-weighted dynamic range of below 6 dBA and up to 110 dBA. All tests are conducted inside a hemi-anechoic chamber with a noise floor close to 6 dBA and an ambient temperature of 25–28 °C. The test subject is placed a meter from the sound analyzer.
Full & 70% Speed
I expected lower noise readings, given the fan’s low max speed.
Speed (Percentage) – Noise
I use a different setup to drive the fan for noise measurements, so there might be a difference in the readings of the Longwin machine, especially in the max fan speed reading.

Hello, great review as always. Will you have a review of the Phanteks D30-140mm?
I have NO contact, at all, with Phanteks. I will see if I can find it from elsewhere.
