What Fan Config can I run in the Lian Li DAN a3 without getting humming or turbulence?

[Akumatie]

This is my current config, with just having the 2 fans on the cooler then the 1 exhaust fan.
I tried putting a fan on the side metal brace to feed the CPU cooler, cool air but that just made humming noises.
Sometimes I also do get humming noises from the front cpu cooler fan for whatever reason I have no idea why and it's extremely annoying so I had to take it off.
So I am not sure if it's the case that is making the fans act this way or something? I don't know if I am missing something.
I have the fans on separate headers, and I have them all of the silent fan pre set in the bios with a 3 second up and 9 second down speeds when temps change.

I had some humming from my DeepCool AK620 at certain speeds.  I always try to have my fans as high as I can without them being audible.

I prefer a constant fan speed at all times instead of letting the fans ramp up and down.

My AK620 would hum at 31% fan speed but at 30% it does not.

I will personally have a little bit higher tempreratures ( Still within safe limits ) than fan noise.

 

I suggest manually setting fan curves this way and see if you can find a good speed where you don't get the humming sound.

I can try that, do you have your CPU cooler fans on the same or separate headers? And do you have them on the PWM or Auto setting?

I have both fans on a Y-splitter to the same CPU_FAN header.

This is my 'custom' CPU fan curve.  Same would be for all my case fans.  I dont use auto-settings. I adjust all my fans individually through a program.
