Test Methodology
Read the updated review on this product here: Phanteks T30-120 Cooling Fan Review – ReCheck!
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

after finally getting my hands on one of these:
it certainly has to spin slower than A12x25 to stay below the noise threshold for me (sub-600 vs over-650RPM) but should be able to still push more air at a higher pressure
as long as you have enough space to squeeze it in at least and that’s not granted
the hybrid mode is just stupid as it only starts up at way above the acceptable level
overall I’d put it closer to PTT line where you don’t care about noise nearly at all and often have some extra space than the A line that it’s put against usually, but also there are many interesting experiments that could be done with both of them (like putting actually usable fans on Ninja could provide much better performance with no audible noise vs the obnoxious Kaze Flex that won’t shut up until they stop or maybe using T30 on U12S/U12A to see how that fares)
