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 close to 6 dBA noise floor and at 25–28 °C ambient. The test subject is placed a meter from the sound analyzer.
Full & 70% 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.

Please compare the Super Flower Megacool 140 to the Iceberg Thermal Icegale Xtra 140 and the Noctua iPPC 140.
Noctua was supposed to send this fan, but they didn’t eventually. I guess they are pissed with the G2 review.
When a test of the Noctua IPPC 140mm 3000RPM for have a fan to compare it ? 🙂
Sent an email to Noctua and weirdly enough I didn’t get a reply. Will talk again to my contact there.
