After going back to re-check the video I discovered a typo. The graph at 6:00 has the titles for the T30 and the NF-A12x25 transposed. The verbalization of the results is accurate: the T30 yielded 36.2 and the NF-A12x25 was at 38.3. Apologies for the discrepancy.
How can a dry topic as a 120mm fan be morphed into a visual and audio delight? Ask machines and more, he's got a recipe apparently! Awesome video like always!
Always love your sound samples. Motor noise, frame resonances, bearings, blade flutters, many reviews skip right over these and they're SO important if you just want a quiet PC (and have ADD/ADHD/OCD where constant whines drive you NUTS ;-) )
The noise is probably due the pull configuration, my guess is that the P28 blades pass closer to the radiator than the other fans. Push would probably be quieter.
That's still on Lian Li tho. Many rad would have a pull or even a push pull configuration, and if the manufacture doesn't state that, it's their fault.
@@MachinesMore would be curious to see if adding in a gasket/spacer between the fan and rad would eliminate that and also increase performance. Most people probably won't do that, but they'd probably be really performant and quiet with a configuration like that.
The improvement of this channel compared to several years is impressive, you will go far for sure! So in conclusion, a12x25 is still the best at a good noise normalized but what about a case fan scenario instead of radiator scenario ? 😊 Imo the a12x25 are not the best anymore in terms of performance on a radiator scenario but...the noise of p28 are clearly unusable so the thing that they can go above 2000rpm is pretty useless 😅 I still prefer SL-INF for RGB fans and for case fans without RGB i still prefer the S12A and the a12x25 from Noctua.
I see Lian Li gives a lot of info on the P28 details, where the state cfm, noise and statir pressure at the 3 modes the fan performs, that way you have a better idea... Correct me if Im wrong, but others only tell you the rpm and cfm at each mode, not static pressure... They are meant for.use on fins array (to push through), static pressure info is most important info for each mode 😊
There's a 180 Hz tone that appears in P28 sound samples at 860 and 1150 RPM, but not the A12x25. Rotational noise from the fan would vary with RPM, but 180 Hz is 3x 60 Hz. I would suggest investigating where that's coming from, and making sure it is actually the fan. If it is, maybe try to figure out how the fan is creating an RPM-independent tonal sound.
The tip clearance is crazy, and it can go up to 2600 RPM? I have concerns on its longevity but Lian Li would know better I guess. The rotor shape and clearance looks extremely promising, it's unfortunate that it suffers from weird noise issues at lower noise levels. LCP and the extremely tight clearance would suggest very low vibration of the fan blades so I can't really tell where the noise issue is coming from.
The noise is a bummer since on paper these things perform and look great... But i guess i can feel less guilty about liking my lian li RGB fans at least haha
One of the limitation of the 2d graph is that we can’t see the penalty of increasing RPM. The perceived noise increases significantly as the RPM goes beyond 1400 RPM, so the suggested sweet spot for max RPM is right around there. As a water cooling fan I feel that the performance at 800-1000 RPM needs to be a bit stronger however.
I just bought this on Amazon, it's not going to come in for about 10 days but I was wondering if you had any experience with these EKWB EK-Quantum Inertia D5 PWM Pump, Digital RGB, Acetal. Previously I bought two of those $20 pumps the ones that are black with the clear Square top. Hooked it into my system and got nothing . I order the second one didn't work either, I took the first one apart and plugged it into the power and unless I physically started the blade turning it wouldn't turn on its own ,but once I physically started it then it would start working. it's my first water-cooled build and this is driving me insane I've alreay refilled and drained my twice and still haven't even got to turn the computer on yet
Can you skip the three step controller and plug a set of three on a radiator into the uni hub? Also, can you change the RGB on the swappable side strips?
Can anyone tell me the cfm at 950rpm?... The t30 and gt2150 move a lot and are quiet at that speed , but I dont like their color, the P28 color looks attractive to me.
In the A4-H2O it’s a bit easier to build a custom loop in this config, since otherwise the rad fittings will be very difficult to access in the tray area. For an AIO though that config is possible, you will have lots of excess tubing to take up.
Who in the world as a regular PC user needs a fan that spins more than 1700 rpm? If people want to end with earing issues, then ok... These Lian Li's seems nice, but they are just another "noise fans". Sorry, Noctua is the king for years and years to come.
Too bad Noctuas are still overpriced here. I would have gone for the A12x25 CHROMAX black but they're going for 55 SGD here while these P28s were only 90 SGD for the 3 pack. Even the Phanteks T30 3 pack was going for 119 SGD.

Any plans to review the new Dan C4-SFX case? I'd love to see a comparison between that and the NR200. Love your content!
Your videos are so great. I just think the color grading should be tweaked away from the odd desaturation and soft focus.
There's a 180 Hz tone that appears in P28 sound samples at 860 and 1150 RPM, but not the A12x25. Rotational noise from the fan would vary with RPM, but 180 Hz is 3x 60 Hz.

Great review, great production values, thanks!
Love the new hair cut
The noise is a bummer since on paper these things perform and look great... But i guess i can feel less guilty about liking my lian li RGB fans at least haha
Great review! I would rather deal with the extra cables of a p12 max than have loud daisy-chainable fans...
I have high hopes for this going forward. Noise optimization would make this fan best in class.
Excellent videos!
Hi! Did you end up testing this in a push configuration? I suspect the noise issues might be related to pull configuration.
what you say doesn't match the graph at 6:03
also, the arctic P12 is at 27mm, is it usable in the case you showed in the vid?

Lian Li: 2 year warranty X 3 fans in a pack = 6 year warranty
OMG home you are wrong, otherwise it's BS
@@John-qc1zv I’m not sure what you mean, but this is just a joke.
Love the sound review
Wonder if it fits perfectly on silver soul 135 and performs similar to T30?

Can you use the rad bracket and push position and still close the top panel of A4-H2O? That's going to be a big factor for me over the T30
Are there 140 mm ones available??
Hi, I have a question about this fan that is it available to be as CPU fan for Thermalright FC140? Thank you very much
P28 Is it best to use a push or pull hook on the radiator?
So if i put a silverstone vida slim 240 rad with these fans, would it fit the Formd T1 V2?
Can you skip the three step controller and plug a set of three on a radiator into the uni hub? Also, can you change the RGB on the swappable side strips?
Yes, you can use the older controller present on AL120 or SL120.
Can anyone tell me the cfm at 950rpm?... The t30 and gt2150 move a lot and are quiet at that speed , but I dont like their color, the P28 color looks attractive to me.
How do these compare to the D30-120?
How did you mount the radiator in that position? I was thinking to mount my aio with the fans on top of the radiator too

almost thick
The noise characterisics arent acceptable

I have all of my fans at 2000 to 2500 and just wear headphones it is no bother at all if you work in a refrigerated area than the noise is nothing

It's rather stupid tbf. I personally have no issues w/ normal fans or the T30 kind of design. The unifan feature is such a gimmick imo.
