As i said, it is unknown for how long you can run the fan with faulty bearing.Do you think these settings might cause any issues with heating or any other new issue?
Everything is possible.Could it be the case that the air pressure inside the chassis from the beginning evolved slowly into this faulty fan issue??
Also, there are no tests made, on the longevity of GPU fans when you have extreme negative pressure inside the PC. Which you had.
The purpose of case fans is not to look pretty, but provide sufficient cooling for the PC components.Coz it looked aesthetically pleasing, looking the RGB of fans through the glass panel ( thats what the guy who built my setup did).
Then it is still severe negative pressure.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.
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.
