A lot of motherboard 4 pin pwm headers do voltage control to for 3 pin fans, 2 of the 3 pwm headers on my asus b350 can do voltage control. I agree you should always get the pwm version if they're the same price, pwm is superior because it uses less power at less than max rpm's which means the pwm fan will run cooler and last longer.

Indeed, can't remember what brand / model motherboard it was, but it had a pressure switch that automatically set variable voltage fan header to PWM when PWM plug was plugged into it.

I got 2 x 140mm P14 pwm pst fans today, very happy with how quiet the bearing/motor is. It's the first fan where I'm not sure I can even hear it "clicking" when I put my ear to it at low rpm. It basically has zero motor/bearing noise at low rpm which is good because fan benchmarks don't/can't really show how low the bearing noise on a fan is.
One thing I've notice is the minimum rpm is 300 instead of the 200rpm listed in specs and it doesn't seem to have a 0rpm mode?(I'm not sure if it's meant to though), can anyone else with the p14 pwm pst fan get the rpm down to 200rpm? 300rpm is surplus to my needs.

That graph it's from a "reviewer" that i would ignore completly.
I can understand the p14 topping out premium fans, but the fractal one is complete garbage, and he has more reviews like this. He is also evaluating the looks of the fans and coolers on a scale, which is a completely subjective matter.

If you tell me the guy is on crack everytime he does a review, i would belive it.

Don't belive everything you see.

This has been said over and over here. This "reviewer" has "results" that never coincide with the results of known good reviewers. His "tests" consistently have "results" that favor the items with monetized links in his descriptions. It doesn't take a rocket scientist or "hardware scientist" to figure that out.

They have afilliated links for every product in the review, just like every modern review. So that's kinda a moot point.

Links don't change the fact reviewer publishes bogus data. ;)

No, but you just said that his test results "coincide" with the products linked, when in fact, he links all of them, completely nullifying your theory that the results are skewed for personal gains.

So on what basis, then, is he publishing "bogus data", whatever that may mean?

As far as I'm concerned his testing method is suboptimal for he only uses a single fan in the entire system, but the results are interesting regardless and certainly not without merit.

I wanna use arctic p12 or f12 for pull in my push pull aio. Which one would be better? Is static pressure so important because I have a high static pressure fan for push? I thought maybe f12 might be better to balance airflow.

You want the P12. The static pressure is important since you are moving air through the resistance of the rad. The F12 is an essentially useless fan unless in an open air application. The P12 is a significantly better fan for your application, and in almost any other application.

Agree with ciarlatano. I have p12 in push/pull on my 360 XE rad - the perform exceptionally well and quiet. The motor DOES have the hum in the range of 1000rpm, but this was beaten to death in this topic.
i have darkside GT on my other rad which being 360 PE in push - i would say the perceivably GTs are moving more air then p12, but are “louder” then p12s at the same rpm range. By louder i mean they do have very little noise coming from the motor at all rpm ranges. I can pick it up because at idle all fans are at 600ish rpms and max rpm i am currently using when gaming are 900rpms, so the system is dead quiet and it is easier to hear noises from motor when its being the “loudest” part of the system.

I asked because the push fan is already breaking the resistance, should the pull fan help with steady airflow? This is probably much more complicated than that including some fluid dynamics.

Just try to stick to the same fans with push/pull config. It’s not a must, but in that way you are making sure that both push/pull work within the same rpm, thus moving same amount of air.
Having different fans “might” ( in huge caveats) cause parasitic resonance that will make the setup louder.
PS: i was running vardars as push and p12 in pull before - i tried to match them not by rpm but rather by cfm they are creating. With vardars my rig was sounding like a rocket which is about to take off. Now with p12 on push/pull it is dead quiet, even at higher rpms as before

All this high pressure fan vs airflow fan is advertising hype.

Airflow is the result of high pressure air moving into lower pressure air. Fan pushes higher pressure air out, and this higher pressure air than move on into lower pressure air. The higher pressure is the more powerful it is, so higher pressure air will flow more air past obstructions than lower pressure air.

As for using push /pull on your radiator, you will see little to no difference in cooling with push/pull vs just push, especially when at same noise level. 4x fans are 3dB louder than 2 fans, and if we speed up 2x push fans to same 3dB louder level as 4x we have the same cooling as with 4x fans at same noise level.

But if you want to waste your money buying more fans, use all p fans already suggested.

You can stop the PWM fans, that's not a problem but they don't always start quietly in all orientations. At least the P12 PWM on my GPU when they are facing down right now don't like much starting up quietly. Facing to the side it was not a problem. That's why a lot of PSUs and GPUs have ball bearing fans, they are oriented intake down and the regular bearings don't always like that in some situation. In operation it's fine, only starting up is a bit of a short "RRRRR".

So if you plan to use fans facing intake down and start stop them it may be worth it to look for the ball bearing ones.

Oh well, if they ever crap out just gonna get the ball bearing ones then or put back on stock ball bearing fans as those are damn nice for sure but not as good cooling as 120 mm regular fans.

The reason I want to add another fan is beacuse I have a pretty crowded sff case (sg-13) and I have no place to add an exhaust fan. I want to add a pull fan to the AIO so I can increase ariflow inside the case and help gpu cooling.
