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

Is there a wiring diagram available for the Alphacool Apex Stealth 2000 fan? We are using in a non-computer application & need to know which wire/pin is ground.
usually the black pin is ground
The Phanteks T130-120 might not leave room for competition, but it’s the only one 30 mm high, instead of 25 as all the others.
Looks a tiny bit unfair this way, if you ask me.
Very good review. Love the page 8 normalized noise tests.
– Woud love a ”real world” thermal test like der8auer did with a radiator too. Lot of numbers, cfm, noise etc but what does it translate in °C ?
– Wish you added to the charts : Noctua NF-A12x25 PWM /// be quiet SILENT WINGS PRO 4 120mm PWM /// ARCTIC P12 Max
And when you hit the max speed for exemple noctua remove it for the later stages.
I usually set my fans 800-1000 RPM idle and 1300-1800 for gaming.
We will add more soon. We are re-testing most stuff right now.
A real-world test would only cover 1% of all possible scenarios because some radiators need high airflow, others high static, and others a mix.
In the real world, you see static in cooling systems and airflow for chassis use.
