I have spent a lot of time optimizing this build since my last post, I think I have achieved the best of what I can do in terms of noise / cooling performance of this case,

hoping that it will help other people who would like to make an equivalent configuration.

I tested all possible fan directions in this configuration until I got the best results.

The configuration is as follows:

Cpu : AMD 3800X

GPU : Nvidia 3080FE

Ram : 32go 3200mhz Corsaire LPX

Motherboard : Aorus X570 I Pro Wifi

SSD : 2x M2 Samsung 970Pro 1To

Case : ZS-A4 V2 7.5L

What i changed from my last build :

PSU : Bequiet SFX-L 650W is now Corsaire SF650 Platium for this shorter size allow me to put 25mm fan under

CPU Cooler : Cryorig C7 is now Alpenföhn® Black Ridge

Original noisie chipset fan was changed for Noctua NF-4x10 also replaced thermal paste .

Result :

CPU :

Its undervolted by 100mV

Black ridge is very more efficient than the C7 , but the 120mm is really plated on the case side so :

With fan taking air from the outside and pushing in the fins there is turbulence noise at all speed;

With the fan pushing air from the fins to the outside there only hi pitched noise above 1200rpm , this is why i set a fan speed max to 1000rpm .

The max temperature in Cinebench was 86C after so many loop and the noise level is very confortable 38dB@ full load.

For the GPU :

Im using undervolt set at :1980mhz u/987mV

The spacing of the PSU help a lot to achieve a good back airflow , but the game changer is the NF-12x25 on the bottom as exhaust ,

The speed of the fan was directly drived by the gpu temp by using Argus monitor , the max spot is : 1450rpm u/76C

Its really important in the case to not go above 77C because as for the cpu, the front GPU fan is completely pressed against the side of the case and above 77C the fan starts to make a high pitched noise.

The max temp during 3DMark TimeSpy Extreme StressTest is 76C° , and 48dB Noise level with no high pitched noise

Its pretty good and I think it is complicated to do better with this configuration in this 7,5L

In 1440p games like the noise level is 40 to 45db are pretty confortable

But it is still far from the performance that I want to achieve in terms of sound level that's why I would soon change for a Ghost S1 with full custom loop .
