Question This noise is coming from somewhere in my PC and I tried all this. Any help is appreciated.

Do you think these settings might cause any issues with heating or any other new issue?

As i said, it is unknown for how long you can run the fan with faulty bearing.

Could it be the case that the air pressure inside the chassis from the beginning evolved slowly into this faulty fan issue??

Everything is possible.

Also, there are no tests made, on the longevity of GPU fans when you have extreme negative pressure inside the PC. Which you had.

Coz it looked aesthetically pleasing, looking the RGB of fans through the glass panel ( thats what the guy who built my setup did).

The purpose of case fans is not to look pretty, but provide sufficient cooling for the PC components.

The case has 3 fans above with exhaust out, 3 fans below ( DIRECTLY BELOW THE GPU FANS) to exhaust air out, and 3 fans on the side ways (AIO Fans) to suck air in.

Then it is still severe negative pressure.

Also, aren't there any rear or front fans?
Btw, what PC case you actually have? Since from description, it sounds like fishbowl case, which is pretty to look at, but in terms of airflow, is terrible.

trust me, i understand it now. and i myself wanna change the fans position but as soon as i opened the back panel, there were so many wires, that i didn't dare to make any changes. my AIO fans are even wrongly aligned with my motherboard, and i have to change them too, but without someone to guide and opening and disconnecting and then reconnecting might just cause more trouble. it was here itself on Toms Hardware that i got the solution for my AIO fans issue.

This is my case. Lian Li 011 Dynamic Evo (https://lian-li.com/product/o11-dynamic-evo/) . A total of 10 fans could be installed (120 mm) and ive 9 installed. the one in the back above where DP port is connected in the GPU is empty. I understand it still is bad airflow, is there anything i can manually do?
