Silent Wings 3 are infinitely better than Pure Wings 2. PW2 are rated 0.76mm H2O @ 1000rpm, much lower than SW3 rating of 1.08mm H2O @ 1000rpm, and pressure rating is what gets air through grills and filters. PW2 fans are almost worthless even at fulll speed.


SW3 high speed are 2.16mm H2O @ 1600rpm giving you a lot more airflow through filters and grills.

 

Well that's all I asked for, perfect infos, also do you know if there's a comparable fan from other brands?

 

Pure Wings 2 is a rifle bearing fan which was the same generation as Silent Wings 2. It's mediocre while the Silent Wings 3 is a true FDB (Fluid dynamic bearing) with top tier performance.


See https://www.overclockersclub.com/reviews/be_quiet_140/3.htm , https://thermalbench.com/2016/03/08/be-quiet-pure-rock-cpu-cooler/4/



I don't think there's been testing on the new faster model 1500RPM Pure Wings 2 (other than on the Pure Rock cooler), but if the bearing is the same I wouldn't expect miracles.

 

Between PW2 or SW3, it's no contest that the Silent Wings are the way to go.

If you are looking for something a bit more budget friendly the Noctua Redux line has some nice stuff, and they aren't the typical poo brown color. 120mm: NF-P12 redux-1700 PWM 140mm: Noctua NF-P14s redux-1500 PWM

Corsair ML120 and ML140 are also good performers

 

As well as Arctics P12/P14.

 

So I've found some fans around amazon, Noctua NF-P14s redux-1500, Noctua NF-A14 5V, ARCTIC BioniX P140, ARCTIC P14 PWM PST, SilentiumPC Stella HP PWM, Corsair ML140 and SilverStone SST-FHP141 v 2.0.

Arctic and noctua looks nice

 

Try finding 12V NF-A14. Out of these your best choice are, descending:
- Noctua A14
- Corsair ML140
- Arctic P14


Forget about Stellas, they're worse than Corsairs LLs, which are already crap.

 

Unfortunatly the PH-F140MP are like 30€ each for some reason, prob no amazon availability.

I've found the Noctua NF-A14 iPPC-3000 PWM (idk if are the ones BroadPwns meant for 12v), looks good, same price as the sw3, but I guess it's gonna be damn loud lol.

 

SW3 are much better than Noctua NF-A14 iPPC 3000 PWM. Those IPPC are industrial fans.

 

Not the industrial ones https://www.amazon.de/Noctua-NF-A14...iser-Premium/dp/B00CP6QLY6/ref=sr_1_3?keywords=noctua+a14&qid=1570736857&sr=8-3

 

If you're okay with the brown color, Noctua NF-A12x25 have a larger RPM range while being the most quiet but are also the most expensive. I'd vote SW3 if you can find them for around 20 Euros, otherwise you might as well get Noctuas for that 25 range.

 

I think I'm going noctua, 9€ less overall plus splitters and extension inside the box.

 

are there any noctua's that have a higher RPM but still retain a good pressure if set lower (variable fan like CPU / high load and a rad)

 

A12/14.

 

ah so 2,000 rpm is the max for that brand eh. Thanks sir!

 

Pure Wings = Airflow.
Silent Wings = Static Pressure.

Use static pressure fans for intake, airflow fans for exhaust.
Why?
Because intake fans has to suck air through dust filters and various of other things. Airflow fans just has to move air, and they work best if there's no restrictions to airflow.

 

I see....so Pure Wings have no static pressure, only airflow. And SW3s have only static pressure with no airflow.

Fans should be labeled as "static pressure" or "airflow" fans, and we should completely disregard P-Q Curves as being just some diversionary tactic to mask the real truth to the way fans operate?

Not to be the bearer of bad news.....but there is a lot more to the ways fans operate in a given environment than than full speed airflow or static pressure ratings.

 

Withthe exception, that Pure Wings 2 are added to beQuiet air coolers and Alphacools Eisbaer AiOs.

 

Got the A14, amazon sent me 2 used fans so gonna refund them... For now the one installed looks to pull more air than the sw3, by "hand testing".

Tomorrow I should receive 2 "NEW" A14, I'll try to make a temp comparison.

 

I understand ciarlatano's frustraion.


Air movement is caused by pressure differential. Higher pressure air moves to where there is lower pressure trying to equalize pressure so both are the same.



Maybe the below explaination will help:

Airflow, or air flow is the movement of air from one area to another. The primary cause of airflow is the existence of pressure gradients. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.[1][2]
In engineering, airflow is a measurement of the amount of air per unit of time that flows through a particular device.
The flow of air can be induced through mechanical means (such as by operating an electric or manual fan) or can take place passively, as a function of pressure differentials present in the environment.

Types of airflow
Like any fluid, air may exhibit both laminar and turbulent flow patterns. Laminar flow occurs when air can flow smoothly, and exhibits a parabolic velocity profile; turbulent flow occurs when there is an irregularity (such as a disruption in the surface across which the fluid is flowing), which alters the direction of movement. Turbulent flow exhibits a flat velocity profile.[2]
The Reynolds number, a ratio indicating the relationship between viscous and inertial forces in a fluid, can be used to predict the transition from laminar to turbulent flow. This number and related concepts can be applied to studying flow in systems of all scales.
The speed at which a fluid flows past an object varies with distance from the object's surface. The region surrounding an object where the air speed approaches zero is known as the boundary layer.[3] It is here that surface friction most affects flow; irregularities in surfaces may affect boundary layer thickness, and hence act to disrupt flow.[2]

Units
Typical units to express airflow are:[4]


By volume

• l/s (litres per second)
• m3/h (cubic metres per hour)
• ft3/hr (cubic feet per hour)

All 3 fans are installed and the pc seems to be cooler!

Temps idle before 35C~/58C~ with the cpu boosting only at 4,280.

Now are 31C~/55C~ and the cpu reaches the max clock of 4,35.

The cooler is in "low noise" mode (2 adaptors) and I didn't touch the old fan curve.

Looks like a win to me!

Thanks everybody for help and tips.

 

Those are some good gains! Congrats

 

I'm surprised so many case companies didn't include better / more fans in their cases instea of poor performance fans and/or not enough fans to give cases good airflow. Seems they would sell a lot more cases with word of mouth and reviews telling others how nice and quiet their systems are instead of user needing to at least add fans and often needing to replace any that come included. Phanteks cases have good fans, be quiet! now have good fans in their cases, but Corsair, Thermaltake, etc. still include garbage fans in their cases last time I checked.

 

I wish they would just not include any fans in the case. Whether it be for performance or aesthetics, most people replace them regardless.

 

Yes, unfortunately, most people don't replace stock fans, and even worse, they don't even want to move them around or add additional fans. They just want a case to work out of the box with minimal tinkering.

@doyll Corsair has actually started to change their direction with the new ICue 220T and ICue 465X cases.

They're putting pretty decent fans in them and the default fan placement is 3 in front and none elsewhere. And the 220T has amply perforated front, while the 465X has the front glass offset by quite a big margin to be able to pull air from all sides.

And on top of that, the 220T is priced incredibly competitively, when you take into account the price of the fans separately.

They've also taken into account the GPU hot pocket due to obstructive PCI-E metal pieces, the 465X has one of the most breathable PCI-E metal pieces I've seen on a case.

Has Corsair improved the quailty of their cases? Last time looked they were not near as well built as Phanteks and Phanteks cases (Enthoo Pro M) comes with 2x good 140mm fans which is all the front venting supports. But one is in back so needs moved to front and costs £84.82 to 220T being £86.57.

Thanks for the heads up. :thumb:

I need to check out Corsair cases agian.

 

Well, LL fan series are as good as mediocre for a very high price. SP are laughable.

 

465X sports LL and 220T sports SP.

 

@doyll NP No clue about case quality though.
@ciarlatano I was convinced 220T had LLs as well, oh well my bad.

Seems the decent airflow performance in the 220T stems from good enough holes in the front and having 3 fans front (plus raw speed).

You do realize that the LL are actually worse than the SP - https://www.techpowerup.com/review/corsair-ll120-rgb/5.html

So, my question remains. Where are these "pretty decent fans" Corsair is supposedly putting in the iCue cases?

These cases are nothing more than the usual Corsair "don't worry about performance, usability or build quality, just give it a look kids will like" products.

 

that's just one review on a radiator, and yes I've seen the review, and yes I've been dismissing the LL and SP for a while, but you're nitpicking here(From all the various types of reviews I've seen on them, they're quite decent for RGB/ARGB fans, used as intake when the front mesh and filter are not horribly designed).

Also even in that test, you can notice that they are at decently quiet compared to rest at 1250RPM and 1500RPM (the reviewer himself mentions that) they don't circulate that much air compared to the other better fans, but the difference is not that big.

Just so I'm not misunderstood here, I absolutely agree, there are tons of better fans, however, if you lower your expectations enough you see these 2 new cases for what they give, admirable RGB aquarium performance out of the box.

They fall in the Thermaltake V71 TG, and Sharkoon TG5 category but they have better less obstructing filters and higher offset on the 465x.
And with the 220T a good idea to not get obstructed airflow with misaligned filter(filter support) and mesh.

 

LLs are bad, every RGB fan below ML are bad.
