Test Methodology
I use an LW-9266 Fan PQ performance measurement apparatus to evaluate cooling fans. This highly sophisticated scientific instrument was 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

I would also like to see test results for the Lian Li P28 120mm fan. I am curious to find out how the P28 fan compares to the other Lian Li fans you already tested. This morning the P28 is available in the USA for $12.99 USD.
Does your equipment allow you to test larger fans? The Lian Li, Lancool, 216 series case that I ordered yesterday comes with two of the new 160mm fans installed in the front panel. The top panel of the 216 models is interesting in that the panel contains the usual slots for mounting either 120mm or 140mm case fans. That is fairly common. However, it also has a 3rd row of slots so the new 160mm fan can be mounted in the top panel. I started searching online and found an official Lian Li store at a well known Asian website. I purchased one 160mm fan for $7.99 USD. Later in the day I found a link to a vendor in the USA selling the 160mm fan for $14.00. The specifications look very good.
Keep up the excellent work you are doing!
IMPORTANT CORRECTION!
The Lian Li 160mm fan arrived this morning and the Lian Li 216 case arrived this afternoon. The 160mm fan will not fit in the top of the Lian Li 216 case. The fan slots in the top of the case are for 120mm, 130mm, and 140mm fans. First, I measured the slots and determined the fan slots are for 120mm, 130mm, and 140mm fans. Then I took a 120mm fan and a 140mm fan from a box of spare parts and verified the measurements. The 160mm fan is actually 170mm. This also means information in a video review I watched was incorrect. I went back and watched the video again just to make sure. I was disappointed. I now have a spare 160mm fan that I bought for $7.99 USD.
Really think you need to test the lian li p28 at this point. Can be had for under $15 regularly (bought mine for ~$12 a piece) and seems to have some rest performance.
Not gonna lie, had higher hopes for these hyte fans. Considering T30s have come down in price this makes it a tough sell.
will try to find some P28s then.
Awesome! Can’t wait.
