Case and Radiator Fan's advice

[Vicious]

So i've been going down this rabbit hole where I'd like to get my PC quiet and cool - Phanteks P400A

My CPU is housed in its new LGA 1700 anti-bending bracket which brought the temps down by 3-4 degrees celsius.

Now, it's time to do the GPU's thermal pads and case, as well, as radiator fans.
Currently installed, is an H115i with its x2 Corsair ML 140mm fans top mounted for exhaust, 3x Corsair LL 120mm at the intake and 1x 140mm at the rear as exhaust as well.

Summary
Top-mounted Radiator with x2 140mm ML's
Rear mounted 1x 140mm Phanteks
Front mounted 3x 120mm Corsair LL's

While fixed at 1100rpm's for the front fans, they have this humming to them which kinda bothers me, it's not loud, but it strikes the left ear haha. It seems my case can accommodate 140mm fans at the front.

So, which brand and fans would you suggest? I'm hearing great things about the Arctic P14 PWM PST's.
What is your personal opinion on fans for this setup - They have to be silent(at least offering good db's) and good airflow.

I dont know shit about fans.. But have you considered undervolting/ underclocking your components. You can drop temps significantly with marginal performance loss. Dont need quality fans if they only doing a couple hundred RPM. Also consider airflow, internal pressure and relaxing your fan curves so that components run hotter but everything is more quiet. Noctua has always good performance to Db ratios but are pricey.

1100RPM is very high if you want quietness. Even the best fans you'll hear at 1100RPM.

I had ML120s before and I'm pretty sure I had them at around 300RPM.

Intake isn't as important as exhaust for cooling, generally speaking, so you can set a less aggressive curve for the fronts.

How many 140mm fans does your case take at the front? You can get more CFM at lower RPM with 3x 120 fans than 2x 140. But if you can take 3x 140 I'd get the Noctua NF-A14, they're very quiet.

Seems the P400A case can take 3x 140mm at the front for intake.

I get you, so maybe set the front fans to 600rpm and the radiator fans (140mm x2) to 1000rpm and the rear 140mm to 1000rpm?

Are you not a fan (hehe) of curves? Why a fixed RPM?

If you haven't yet, try Fan Control: Home - Fan Control

It allows you to set fan curves inside Windows, without having to go into BIOS.

Even at 1000RPM exhaust, on a hot day in a demanding game you may exceed the capacity to exhaust heat from the case. Curves are safer, for that reason.

Thank you for the application - I've been looking for one!

I don't mind a fan curve at all, let me take it 'for a spin'

Got dem curves going, sounds wrong, anyway, one fan isn't being picked up weirdly enough, but it is in the BIOS.
set the temp to 45 C at 15% fan, ramping up to 70 C at 70% - Currently, the CPU is idling while working at 34 degrees celsius, and it's pretty damn hot in this room.

My ears are a bit blessed, I might add.

Keeping the Rad's fans at 1000rpm, I don't really hear them, it's the front fans that had that humming
