Phanteks T30-120 Fan

[VSG]

Interesting, I might buy these instead of noctua fans in the future.

Can't go wrong with either option, but also the NF-A12x25 Chromax will release sometime to further complicate things.

 

[LocutusH]

Eloops are the most overrated fans in the world

Even more overrated than GTs

Still doesnt make it true, that good 140mm fans are MIA.

How is the radiator fitment? I have Toughfan 12's and fitment wise they are horrible, lots of holes for leakage even with a foam gasket on the radiator. On my next build I was just going to use A12x25's due to the included rubber gasket but this looks like a much better fan.

Hah I know what you mean, I am looking at the Toughfan 12 on the radiator right now. This one isn't bad courtesy the rubber dampening pads on the corners that also allow for some leeway in the uniformity of installation pressures at each corner, but the great equalizer is that massive central hub anyway. Running these in pull is recommended.

Should I swap my Toughfan 12s for these? Eager for the comparison! My NR200P is fully outfitted with them ^^

Nah, not worth it even for decent performance fans and that's a pretty good set you already have.

What are you trying to say? Eloops are not good fans and it's really absurd that people still believe they are good.

They are borderline unusable if you have even remotely functioning hearing.

lol show me on the doll where Noiseblocker hurt you

Sorry I have R9 290 trauma

Please, find some good old Gentle Typhoons to throw in the comparison....

Sigh.. You strike a nostalgia tune here. They have been in my loop for almost 10 years without any trouble.
I think Gentle Typhoons were great for static pressure and tightly finned, thick rads.
T30-120 seems like a great all-rounder. If it had ARGB, that would be definitely the choice for my next build.

The Darkside GTs in the review comparisons are Gentle Typhoons.

Awesome review! would love if you can add the P12 to the list, its very popular with budget builds and has decent performance too.

These look really great, and check a bunch of boxes, performance, and performance modes, daisy chaining support, and they are black. When are these things going to be available?

 

[Operandi]

What no mention of the fan affinity laws?

Also, instead of shopping at PC shops for fans, if you want good fans/selection sometimes its better to go to an electric/electronics wholesaler and buy
-sunon
-panasonic panaflos
-sanyo denke
-deltas
-nidec
-Adda

etc etc

https://www.newark.com/w/c/cooling-thermal-management/fans-blowers/dc-axial-fans?supply-voltage-vdc=12v&fan-frame-size=119mm|120mm

Thats what I do. If you see a good fan in the consumer space, a really good one anyway its made by one of those companies anyway. I just wish one of them would release their own 140mm to the wholesaler market.

Great job VSG!
Its about time someone truly put some pressure on noctuas ippc line up and these seem to be doing just that. Definitely looking forward to a head to head at some point. Thats obviously what phanteks aim was with these beasts. Look out ippc 2000 and 3000, phanteks is comin for ya! If only these came out two years ago when i bought all off my ippc 2000 120/140mm fans with matching phantek halos!
Almost forgot, Sunon is a name i haven't heard in a looooong time! Ive got a box full of 80 and 92mm finger decapitators. Loved those badboys but they were loud. Every last one still works like a charm and they are at least 15 years old. If Sunon still cranks out quality these t30s should be keepers.

Whens the last time you were excited about a fan?

May I ask a question ?

( My calculation might be wrong, Please correct me if I am )

Isn't dBA a logarithmic unit and CFM not a logarithmic unit ?
Dividing those isn't a fair comparison ?

For example for the 750rpm chart
A12x25 19.8CFM 27.2dBA
T30 20.6CFM 27.9dBA

-Noise normalized on numbers only-
A12x25 = 19.8/27.2 = 0.7279
T30 = 20.6/27.9 = 0.7383


If Convert dB back to sound pressure / sound intensity
27.2db = 0.000458174 Pa = 5.248075e-10 W/m2
27.9db = 0.000496627 Pa = 6.16595e-10 W/m2

Put the zeros away

in the case of sound pressure
19.8 / 458174 = 4.32 e-5
20.6 / 496627 = 4.15 e-5

in the case of sound intensity
19.8 / 5.248075 = 3.77
20.6 / 6.16595 = 3.34

In both cases
The A12x25 had a higher value.
So the A12x25 generates more CFM with less sound pressure/sound intensity

 

[erocker]

I'm ready to sacrifice the RGB fans up top in my case for these.

So the A12x25 generates more CFM with less sound pressure/sound intensity

But the more CFM you have, the more noise, if you compare both fans with different speed:
T30 1000RPM 30.6db 26 CFM
A 12x25 1250RPM 32.8db 28.9 CFM
T30 is much better

Also at 1000RPM to 1250RPM you gain:
A 12x25
24.2->28.9 4.7CFM
29.1->32.8 3.7db

T30
26->30.9 4.9CFM
30.6->34.1 3.5db

so the comparasion depend and I think the best comparasion will be when both are equal at CFM or db and not only at one speed, but wide range of speeds

edit: if we get the diff:
4.7 / 2.6 =1.8
3.7/2.6 =1.42
->
24.2+1.8 = 26
29.1+1.42 = 30.5

noctua is better theoretically with 0.1db, but with different speeds we will get different results, I am lazy to do this for each speed

I am pretty sure you might have misunderstood my post.

Since dB is a logarithmic unit , it is not 1 to 1 compare to non-logarithmic units
For example a 3dB difference would mean a 2x sound intensity, and a 60dB difference would mean a million times of sound intensity

A12x25 going from 29.1dB to 32.8dB is a sound pressure from 0.000570204 Pa to 0.000873032 Pa, or Sound intensity from 8.128305e-10 to 1.9054607e-9
T30 going from 30.6dB to 34.1dB is a sound pressure from 0.000677688 Pa to 0.001013981 Pa, or Sound intensity from 1.1481536e-9 to 2.5703958e-9

You can tell by the difference in those numbers
If we shave the zeros off
A12x25 needs 3.03 unit increase in sound pressure, and 1.09 unit increase in Sound intensity to generate 4.7CFM
T30 needs 3.37 unit increase in sound pressure, and 1.42 unit increase in Sound intensity to generate 4.9CFM

Divided CFM with those numbers,
A12x25 gets 1.55 and 4.31
T30 gets 1.45 and 3.45

So if comparison between the numbers you have chosen.
The A12x25 generates more CFM per unit of sound pressure/ Sound intensity increase.

I am not also, but I think scale the resutls to get same CFM or db is better comparasion, because you don't need to compare the fans at different CFM and db

i made same scale for 1250->1500 and at ~1342RPM noctua will lose to T30 at 1250RPM. Since T30 scale better with higher RPMs and at 1250RPM is already better I think at 1500-3000 T30 will gain more advantage, while noctua will be better in 750-1000.

T30 generate 0.1 db more with 1.1 CFM at 1250->1500RPM

1250RPM to 1500RPM:
A12x25
28.9->34.4 5.5CFM
32.8->36.4 3.6db

T30
30.9->37.5 6.6CFM
34.1->37.8 3.7db

And when we increase the speed of A12x25 from 1250 with 92RPM ->
250/2.7 = 92.6
5.5/2.7 =2.03
3.6/2.7 = 1.33

T30 1250RPM
30.9CFM
34.1db

A12x25 1342RPM
30.93CFM
34.13db

I'll wipe the smile off the faces of the arrogant Noctua engineers.

 

[Ferrum Master]

You should add no RGB BS as a pro in the conclusion.

Do they have motor noise at low RPM? Ticking or other sort of harmonics besides the ones that are caused by blades. For example like Vardars do. Typhoons at low RPM has it too, but is a bearable hum like coming form a V8 exactly as you add RPM you can hear the motor struggling.

T30 generate 0.1 db more with 1.1 CFM at 1250->1500RPM

1250RPM to 1500RPM:
A12x25
28.9->34.4 5.5CFM
32.8->36.4 3.6db

T30
30.9->37.5 6.6CFM
34.1->37.8 3.7db

I mean
Because dB is a logarithmic unit.
Same amount of difference of dB does not mean same amount of difference in sound energy

32 dB to 36dB
34 dB to 38dB
are both 4dB difference.
But they are not the same amount of difference in sound energy.
34dB to 38dB is a much greater difference.
