Cooling my PC better?

My setup is listed above. I have a 550D silent case on Noctua air, I like the silence, however I was thinking of upgrading the case fans I currently have to improve airflow through the case. I have the original fans that came with it in there currently, but I was wondering how much better it would be if I upgrade the rear fan from a 120mm to a 140mm and get higher flow 120mm front intakes as I can't upgrade those to 140.

I have removed one of the drive cages to open up airflow a bit, but if I can get some suggestions on better fans, not just silent, but that move a lot more air without becoming full on loud turbines it would be nice.

I wish Tom's would do case fan reviews in the same way they do CPU coolers.

Thanks in advance for any advice,

Honestly?

In my experience more expensive fans cost a lot more money.

Fancy blades and shrouds, little nubs and spoilers and dams all over the fan, they really do make them look cool…

But in my honest experience, a clean, black fan, with a quality resistor to slow it down, performs just as good if not better than a lot of the more expensive fans on PWM and controls. And when I say better - I mean for the money. A cheap Xmigatek fan will cost 1/12th that of a Noctua. A Noctua may be a few percent quieter or move a few percent more airflow, but not 1200% more, that is for certain.

Realistically there are only a handful of fan types.
Sleeve, single ball, and dual ball. There are variations like “hydro dynamic floating range mumbo jumbo” but they really mean sleeve.

Because they all have contact and moving parts, they all make noise.
Any noise reduction claimed by various brands comes from magically making air molecules not create sound when they jostle. Whether you buy a blaze orange Cougar, a brown Noctua, or a grey Corsair, the differences between those and a cheap black fan that hasn’t changed in 20 years is minimal, if any.

With the parts your using the stock fans you have should be adequate.

My big concern has always been with heat getting out as opposed to building up in the box. I thought a 140mm at the rear would at least clear out more of that heat. Particularly considering the CPU cooler fan 150mm blows directly at the 120mm fan currently at the rear. And if I'm going to pull more out, might be good to let more in from the front.

Maybe I just need to adjust my fan profiles to increase the speed of the rear fan at all times and increase the speed of the front fans when the CPU temp increases. Might need to play with SpeedFan but I still feel like I need a 140 at the rear rather than the 120, but then I get worrying about positive air pressure.
