Keep in mind if the 5 packs are relatively cheap like the F14's. Then we might have new value king on our hands.

On the other hand. Looking at the design. Seems similar to something cooler master has. A quick google search and you'll know what I'm talking about.

How do you know the static pressure ratings are 'anemic'?
Have you actually tested any of these fans to see what their static pressure actually is?

Of course any restriction to airflow will result is much lower airflow than the specs., especially if not running fan at full speed. Specified airflow is unrestricted flow .. so unless we are using fan running at full speed blowing air around a room we will never be getting full airflow. Even at full speed with your

SanAce I'm guessing when mounted in your case it's flowing 80-85% of it's rated CFM at full speed .. because the way SanAce gets it's CFM and mm H2O rating is the same way all these other fan companies get theirs .. although some to cheat a little by artificially 'balancing' the airflow to be identical on both sides of fan when in actual use the intake side will be ever so slightly lower pressure than the exhaust side.

Arctic posted the specs on their fans.

SanAce publishes the methods by which they measure their fans specifications here:

Please tell me specifically how they're "cheating".

Could you please give me the link to Arctic F series fans, specs static pressure rating specs? I can't seem to find it. I find 2.85mm H2O static pressure @ 1950rpm for Bionix 140mm and P14 is 2.4mm H2O @ 1700rpm, but an't find static pressure rating of any F series. 2.85mm H2O and 2.4mm H2O are not 'anemic' to me .. even 1/2 of those ratings while not great is not really 'anemic'.

I think you are misunderstanding what I posted. I did not say SanAce is cheating, I said some fan companies cheat the way they gather data.

Last half of last sentence in my posts reads
"although some to cheat a little by artificially 'balancing' the airflow to be identical on both sides of fan when in actual use the intake side will be ever so slightly lower pressure than the exhaust side"
The third word 'to' should be 'do', but the key word is 'some' as in 'some fan companies'.

I found the perhaps first test review of these new fans, but it's in German:

https://www.hardwareluxx.de/index.ph...hen-druck.html

The review setup seems to be pretty good the way I understand it. There's photos about what stuff they used on page four.

The fans then seem to be pretty good fans. The P14 with its price should be a good choice for anyone, the "Bionix" version maybe not. Here where I am the Silent Wings 3 High Speed are the same price as those Bionix P140 right now. The P14 are about half the price, and there's 5-packs where a single fans is getting kind of close to just a third of the price.

I had updated the first post with 2 reviews I found earlier
edit: as far as pricing goes what I've seen on Amazon makes it only compelling in a 5 pack.


5 pack of P12 is $31 / €28
Cheapest P12 for single fan ~$12 / €6
Bionix P120 = $16
P14 ~ $13 / €8
Bionix P140 ~€18
5 pack of P14 = €41

Oh, I didn't look at the first post. An edit perhaps doesn't pop up in the thread subscriptions, only new posts?

Very interesting bit of testing. Thanks for posting the link.

While the full speed, free airflow, grill, grill & filter and H5 flow rates and db data tells us little. But the 1000rpm radiator flow is very helpful showing use Arctic P series are as good as NF-A14 and ML140 with only Silent Wings 3 having better airflow (which many of us already know is true). But when I look at the sound pressure levels on radiator at 1000rpm and see Silent Wings 3 being 7dB louder than Arctic P series I started scratching my head and wondering what is going on here. Silent Wings 3 also has significantly higher airflow I'm not saying it isn't true, it does give me cause to wonder. I would be much less skeptical so I can understand noise level being somewhat higher too .. and if the difference was 2, 3 or even 4dB difference it would seem possible. But Silent Wings 3 being 7db louder on radiator at 1000rpm makes me wonder. Maybe they made a mistake in or their test equipment gave them a duff sound reading for P series and/or SW3, or maybe it's because SW3 is flowing 12m3/h more air and that is the cause, I don't know, .. but their 7dB difference between them does make me wonder.

I wish we had performance comparison of fans at same cfm airflow instead of just fan speed. That would give us a much better performance comparison than fixed fan speed .. but it's also more work for reviewer ...

Whats the verdict on these fans? I'm planning to replace the mismatch of fans in my case with all the same model and noticed the Arctic P12's are available in packs of five for £15 for 3 pin, or £25 for PWM PST.
The PST version looks particularly useful to reduce cable clutter.
