Your question is like asking what is best tire, just need traction on asphalt track. . Obviously it would be a drag racing slick.
What size fan? 120mm, 140mm or bigger? Best 120x38mm will be something like Nidec Servo G1238B Series 5300rpm and 6300rpm fans with up to 67 dB. 260cfm and 53mm H2O rating. They also make 172x150x51 D1751M series fan is 2800rpm, 49dB, 205cfm and 12.19mm H2O rating .. and 172x51 D1751S with up to 6800rpm, 64dB, 501cfm and 65.278mm H2O rating.

My basket at Overclockers UK:
- 1 x be quiet! Silent Wings 3 120mm PWM Fan= £19.99
- 1 x be quiet! Silent Wings 3 120mm PWM High Speed Fan= £19.99
Total: £48.68
(includes shipping: £8.70)
I run my rig without sound from headphones or speakers so silence was key along with performance . If you can find one that provides as much static pressure, Air flow to db , please let me know - although they do cost !

For your application and only on OCUK, I'd imagine nocuta industrial or one of the high rpm ek vardar models. (evo and original)

I just found this thread via search as I'm also looking for high airflow fans and don't care how noisy they are. I've got 4 of the Noctua Industrial fans installed on my radiator just now, but they don't even hit 2000 rpm at 100%. I'm thinking of picking up the 3000 rpm models.

One downside is that they don't have a 0 rpm minimum. Is there any fan that can push air at 3000 rpm and also have a 0 rpm minimum?

Surely every fan has a 0 rpm minimum? When the fan is off.

Noctua PWM fans have a 20% minimum, and the motherboard can't make them spin any slower unless they are set to DC mode.

No. PWM fans can only be commanded to their minimum, or off. The minimum rotation for your PWM fan usually 30% of their top speed. So at 0% they are off and at 1% they will be 30%, 2% they will be 30% and so on. Only then they are commanded to something above 30% will they actually go to that commanded speed. The corsair ML series are exceptional because they will go down to 20%. The corsair are a good fan but they only have a top speed of 2400RPM. The Noctua shift far more air because they run all the way to 3000RPM but ( probably, I don't know for sure ) have a minimum speed of 1000RPM. It may be an option for you though to get the corsair since they can be controlled at lower RPM?

@Pocah the Noctua go to 20% also (I already have the 2000 RPM version).

I have these and not many will perform better.

Extended range means they operate between 25-100% but also feature something called 0db regime.
If you want something that spins faster then you also have these.

@Doobedoo the furious Varder look just the ticket. Although, it looks like they don't support the 0rpm option?
I'll pick some up shortly and see what they're all about.
Cheers.

Quite a bit cheaper too. Why do you need 0 rpm? Would you be mounting them to your external rad?
Soldato
Yes, I'd be mounting them to the external rad and I'd like that to be passive until it gets called into action.
Permabanned
Why not just use the 120 ER's. I'd imagine 2200 rpm will be plenty for your needs. I don't ever run mine above 1400rpm with internal rads so your external shouldn't ever really need 3000rpm.
Either that or use an Aquaero with a water temp sensor to monitor and control, you could shut the fans down below a certain temp and have them come on when it goes above.
Soldato
This is my set up: https://forums.overclockers.co.uk/threads/external-rad-at-window.18794221/
I control them with a water temp sensor which is plugged into my motherboard and the fan curve is set according to water temperature. I'd like them to be 0 RPM on idle as it'll ensure the water temperature stays close to 20C. I would also like them to ramp up to 3000 RPM on load as it means I can take full advantage of the fact I won't hear them and it'll give me maximum movement of air.

I can completely turn my fans off using an Aquaero meaning the rads run passive until they reach a certain temperature then they will spin up at what ever rpm I tell them too.
It will give you much greater control than your motherboard can. You can have ambient temp sensors and water temp sensors and set your fans to maintain a delta between the two.
I'm not sure I understand why you would ever need the fans to spin at 3000rpm to be honest.

I'll do a little research into the Aquaero.
I want to run them at 3000 because I can do that without having to suffer the noise or the expelled hot air. That's why I mounted the rad remotely, I don't even know it's there.

I get that you can but do you need too? You have a 480mm external rad plus a 240mm internal rad cooling just a gpu, even in the summer I doubt you'll need 3000rpm fans to keep the temps low. Seems a bit overkill to me but hey ho.
