why are so many pc fans loud but ineffective

[PurpleFencepost]

i swear i just bought this new case supposedly with "ultra quiet cooling" and the fans sound like a damn airplane taking off but my cpu temps are still creeping up halfway through a game. like what is the point of all this airflow design if it doesnt actually cool anything?? is it just for show or something? i get that you need good cooling for high end builds but it feels like theyre prioritizing looks over function at this point my last build from like 5 years ago was quieter and kept temps lower with way less fuss sometimes i think about switching to passive cooling just to avoid the noise but then i remember how bad that was back in the day too. idk man it just feels like we shouldve figured this out by now. ...
