Test Methodology
I use an LW-9266 Fan PQ performance measurement apparatus to evaluate cooling fans. This is a highly sophisticated scientific instrument made in Taiwan by Long Win.
Fan Testing Machine Technical Specifications:
- Manufacturer: Long Win Science & Technology Corporation
- Air Flow Rate: 2.4 – 250 CFM
- Accuracy of Air Flow Rage: <3.5% INFS
- Repeatability error: < 2%
- Static pressure: 0-20mmAq (100mmAq with the high static pressure throttle device)
- Overall Dimensions: 0.7 (W) x 2.2 (L) x 1.6 (H) m
- Power Source: 220VAC, 5A, Single Phase, 50/60Hz
- Based on Standards: ISO 5801-2007, AMCA 210-0, ASHRAE 51-2007, IEC 61591-2005, GB/T 1236-200
Besides the Long Win machine, I also use the following equipment.
Testing Equipment:
- Noise Test Environment: Hemi-Anechoic Chamber with 6 dB(A) noise floor
- Conditions: 25 (+-2) degrees Celsius, 40-50% humidity
- Sound Analyzer: Bruel & Kjaer 2270-S G4
- Microphone: Bruel & Kjaer Type 4955-A
- Mic Calibrator: Bruel & Kjaer Type 4231
- Data Logger: Picoscope TC-08

Great review as always, thanx
One small typo on the 2nd site, last sentence. There should be superior.
…not the 1st typo in this exact word … I have two guesses for the reason:
1st: superior in Greek = ανώτερος [anóteros] …phonetically close prefix an ≈ in…. or
2nd: you work too hard (almost every day one YouTube video and one review + other activities) … you should rest more, not just work … in Slovakia we have a saying… work is not a rabbit, it will not run away, it will wait at you … 😊
thank you! No rest for me 🙂
Great work, thanks!
P14 max are available now, do you have plans to test it anytime?
Yes, waiting for it to arrive from Arctic.
