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

For the readers, i had Arctic 4× P12 Max and replaced them all with thermaltake toughfan 12 pro (45€ for 2×120mm and they exist in 140mm too). The build quality is really good and i would say same motor noise as noctua. Arctic it was an unpleasant experience ! Check the Nomalized Noise Tests on the recent 29/12/2023 Noctua NF-A12x25 PWM, the toughfan 12 pro are in the charts. Btw i’m curious, you include the 3×Phanteks T30 at 90€ why not the rest of your data ? I prefer to have the big list to peruse.
Anyway thanks for the excellent review like always. It is a good budget fan.
Hi, did you replace the P12 Max? For the Phanteks, I have the full review in the link, and they are included in the charts. I am curious, though, to hear what were the problems you had with the P12 Max.
about daisy chain options. This is what they say about this on their subreddit:
“We decided against the PST function for this fan due to the higher current.
Each fan is taking around 0,3A.
Most Motherboard-headers offer 1A. If you combine these fans with a Liquid Freezer you’re hitting the 1A pretty fast.
Alternatively, we recommend our 4-pin PWM Fan Splitter Cable or the Case Fan Hub.”

The Super MegaCool requires even more current but it has a daisy-chain option thanks to a special adapter it has, to draw power from a SATA connector, so everything is possible 🙂
yes, i know it and completely agree. But tell this to Arctic please 🙂
Great review! Did you mean to say ”superior” here?:
”It uses a double-ball bearing, which is inferior to FDB and HDB at high operating temperatures but is typically noisier.”
Thank you! Fixed!
Well, one note to this theme, it depends on the color.
The black one has dual-ball (double-ball) and the white one has FDB.

It would be nice to compare them.
Noted! I don’t have the FDB P12 Max, but I can ask to send them.
I actually have it, just checked the samples they sent me. Same RPM, noise looks similar, so I don’t expect any tremendous differences in performance.
I can’t help myself, but my internal DB-meter, which is located in/on my head can clearly hears sound of the dual-ball bearings (I believe it’s somewhere around 4.5 to 5 kHz) in your recordings even/or especially on low RPM levels (10% and 25%) or here:
https://www.youtube.com/watch?v=KQDJBl32QZ0 or here:
https://www.youtube.com/watch?v=l33V4mTN2BI (similar to TL-B12 Extreme)
And Arctic lists the exact same characteristics for 2 products with different bearings, which is strange. It would be easiest for the producent to use a cheaper type of bearings if that was the case.
…
But I understand your point.
Having a DB meter so close to the fan means that you get part of the airflow’s friction into account. This is why there is a specific quideline available on how you measure IT equipment.
I comment the YT vids you mention.
The same looks strange to me, too. Exactly the same performance etc, although different bearings.
This is what I will do next, I will take another Black P12 Max (DBB) and compare it with a White P12 Max (FDB). Because also from fan to fan sample there can be notable variations.
Thanks, I am appreciating it.
one note: „my internal DB-meter, which is located in/on my head“ …was kind of a joke … I meant my brain/ears :-D, and I noted the sound only from your and other recordings. I have no PC fan with dual-ball bearings (my PC fan portfolio consist of FDB/HDB … P12, TF 12 PRO, NF-A14 and Zephyr 50)
(there was no Replay button, hence the new thread … this message can be deleted)
Your ears, if they work well 😀 are the best db meter since they can go down to 0 dBA!!!
