Noctua NF-A12x25 for open air case fan or something cheaper?

Like a lot of us, I'm looking to keep my PC as quiet as possible while maintaining low temperatures, especially now that I'm working from home all the time. I naturally got a couple of NF-A12s for my radiator but, for "open air" low resistance fan locations, such as the rear exhaust of the case, is it worth it?

I've been considering the be quiet silentwings 3 instead but they are almost as expensive as the NF-A12s so I feel I might as well get the Noctua (despite their color scheme not quite matching the rest).

I've also considered the Arctic P12 PWM but they seemed geared more towards higher static pressure situations. They might still be good, though.

Any other fans I should consider? Should I just get more Noctuas?

For open air you want whatever has the highest CFM at the lowest db you can handle. Noctua's likely do have the best CFM/noise ratio but at a very high cost.

No.
Silent Wings 3 PWM high speed are best fan I know of. They are definitely better with a more pleasant sound when audible than others, even Noctua.

Fans with high CFM and high mm H2O flow about the same as fans with high CFM and low mm H2O in open use. That means no filters or fancy grills.

I believe be quiet! Silent Wings 3 PWM high speed will have best cfm to noise ratio.


Much depends on where on Earth you are because what I can get is likely not the same as what you can. Some links to where you buy would be helpful.

Depends, I've had Silent Wings 3's, Corsair ML and various other brands and models and the NF-A12x25 has a unique sound signature, very similar to Gentle Typhoons (also known as Nidec Servo fans) meaning they can run full speed at 2000RPM and still won't produce any noticeable wind rumble like for example the ML's do.
Keep in mind they Noctuals will get very, very costly if you'd want to expand and keep the same model.

A lot of good points here. Much appreciated. I'll need to think about it some more.

I'm in the US so I'd be buying from Newegg or Amazon.

Good old Gentle Typhoons. Good to know about the sound signature.

PS. I don't plan on running these at a high RPM. Most likely under 1400, if that makes any difference to anyone's recommendations. I'm very focused on silence.

I ordered one silentwings 3 PWM high-speed to test out. I don't plan on running it a high RPMs but, it appears there's a big RPM drop-off that occurs with these fans when dropping the PWM from 100% so I decided to go with the high-speed to compensate. I don't know if I'll have that drop-off issue with the Corsair commander pro but, better be safe. I hope the fan has no issues running at low RPMs.

The PWM control problem is with only a very few controllers, aquaero being the main one.

Considering he is asking for no restrictions case fan, probably, he'll never run them past 1000.

OP

Take a look at schyte kaze flex. The 1200 seems to have good numbers, they sound great and they're not bad quality.
In spain i can get my hands on them for 10 bucks each.
