Recommendation: 140mm fan for radiator?

Hi everyone!

I’m looking for an upgrade to my fan setup. I’m unhappy with my water temps and I’m pretty sure that my intake fans do not perform good enough. First things first. The relevant specs:

- 5900X (watercooled) - 7900XT (watercooled) - 1x 420 Rad, at intake (front) (thickness 30mm) - 1x 280 Rad, at exit (top) (thickness 30mm) - Phanteks Evolv X - Fans on intake: 3x Phanteks PH-F140MP - D5 pump

Those fans on the exit-rad and back are definitely better. I think the biggest “bottleneck” is my insufficient supply of fresh air. Since those three intake fans are mounted in between a dust filter and radiator, it is obvious that they struggle to build up pressure and maintain a good flow. In addition to that: I really want my system to be as quiet as possible while not throttling my components. But my water temp exceeds 47°C and gpu hotspot can be as high as 92°C. So I either increase the fan performance (maybe new fans?) or replace those fans AND the front radiator to a thicker one. But I find it hard to find a very good performing 140mm fan who can handle a rad and dust filter while being below 40dB.

I took a look at those fans already:

- BeQuiet Silent Wings Pro 4 - Arctic P14 argb (because somehow the argb variant is way better than the normal p14 pwm) - Phanteks D30 (mainly because it has a revers variant and I could install them in a pull config while not looking ridiculous) - some other fans that have been proven to be bad on rads. therefore irrelevant

Well, I don’t need a fancy rgb fan if it’s sandwiched (filter -> fan -> rad). Just a black fan (or gray if you recommend me sth from noctua 😂). But I must say that those D30s really do look sexy.

Random people’s opinion, go!
