Hi.

I'm going to change the fans of the radiators as they seem very weak. 1800rpm and static pressure of 2 mm H2O.

I have this options on mind:

Arctic Bionix p12. 2,75 mm H2O (@ 2100 RPM). 12€.

Be quiet! Silent Wings high speed 3.37mm/h2o (@ 2200rpm). 20€.

Noctuas industrial 3000rpm. 7,63mm H2O (@ 3000rpm) 25€.

Noctua A12x25. 2,34 mm H2O (@ 2000rpm). 29€.

Noctua f12. 2,61 mm H2O (@ 1500rpm). 16€.

The bionix is by far the cheapest but not sure if it's worth it to spend more in the other options.

Noise is important (noctua 3000) but it can be reduced all of them for a sweet spot.

The idea is at the same speed which one will work better. Sound is second important here.

If its not worth to change the stock one let me know as well. Stock radiator-fans seems cheap but at the moment do the job decent.

Any suggestion?

    The stock radiator fans are garbage, they have horrible "blow back" because of how their blades are, that's why their pressure is so weak.  As I've posted in both the main queue & Kingpin queue threads, I highly recommend replacing them as soon as people get their Kingpins.  They're significantly worse in terms of airflow etc than the FTW3 Hybrid radiator fans.
    If you're okay with having to level off the noise, the Noctua Industrials are the way to go.  EK Vardars are also great, and around the same price.  If you don't care about noise at all, running either of those two types at max/near max will get you waaaaay better airflow than the stock fans.  I think my temps at comparable RPMs dropped 3-5C on the core under load, because of the better airflow of the better fans, then going Push/Pull dropped me even further.  I don't go above 50-51C in games even as stressful as Cyberpunk is now, typically it stays in the 48-50C range, occasional peaks at 51 for a few seconds, and that's with the fans peaking around 1800RPM which is not at all loud... compared to with the stock fans, they'd get up to 2200RPM or whatever their max was, be loud as heck, and the GPU would get up to 55-57C.
    And, the cherry on top: That 51C max temp is with a 2160MHz @ 1068mV OC/undervolt, drawing up to around 480W peak load, and a 1000MHz VRAM OC (which is relevant with how the coldplate links to the memory plate on the face side of the card so it is dealing with that heat too, half of it anyway).  
    Basically, if you can go Push/Pull, get 6 of the highest air-movement fans you can, then adjust it so that they cap out in speed where the noise is just below where you can't stand it anymore, for the speed it'll go to starting at 50C - stepping down to like 1000RPM or so when idle (mine I have idle at 920-970RPM & I still idle at 22-24C depending on ambient temp).

    Thank you.

    I went down the list to the Noctua 3000, the A12x25 or bionix.

    The EK Vardars are not in amazon Spain so I'm more limited.

    I'm just afraid of the Noctuas industrial 3000 because of this video: https://youtu.be/dsG5U7rw4Z0
    That noise seems to be very disturbing (three of these together).

    The noctua A12x25 are the most recommended but the price for 3 is 90€. The Bionix have a very good price 36€ for them.

    What to do?

    I replaced the stock ones (Pro Logic crap) with the Bionix p120. I ordered in Amazon so I can return them.

    I set both fans at 100% speed to test and the Bionix p120 have 2°C more than the stock ones. Noise is ok in both.

    So I guess I have to go for more static pressure than the Bionix p120 (2.65).

    A) EK Vardar evo 120ER. (2200rpm)
    Max Air Flow: 77 CFM = 131 m³/h
    Static Pressure: 3.16mm H2O
    Noise Level: 33.5 dBA

    B) Silent Wings 3 High Speed. (2200rpm)
    Air Flow @ 100% PWM / 12V (CFM / m3/h) 73.33 / 124.58
    Presión de aire @ 100% PWM / 12 V (mm H2O) 3.37
    Nivel de ruido @ 100% PWM / 12 V (dB(A)) 28.6

    C) Noctua NF-A12X25. (2000rpm).
    The static pressure and specs are worst than the ones above but reviews are all going for them because of the noise.

    D) Noctua industrial 3000rpm.
    Airflow 186,7 m³/h
    Sonoridad 43,5 dB(A)
    Presión estático 7,63 mm H₂O
    This Noctua are best specs but they have like a rattling noise which is hard to digest for what I heard in YouTube.

    Which option will improve the Bionix P120 best?
