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 work, thanks!
P14 max are available now, do you have plans to test it anytime?
Yes, waiting for it to arrive from Arctic.
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 🙂
