Did you have no success upgrading your fans (Noctua etc)? Still too loud? How about water cooling?
The CPU is AIO (and the radiator fans are loud). The GPU has very loud fans too, but is not AIO.
It's four years old at this point and I might just build something else rather than try to retrofit this one to sanity (which I doubt is possible without dumping the GPU anyway).
The GPU still gets kind of loud during intense graphics gaming sessions but when I'm not gaming the GPU fans often aren't even spinning.
The CPU fan is rarely an issue (it mostly just goes bananas when IntelliJ gets its business on with gradle on a new project XD).
The GPU is the main culprit and I'm not sure there's any solution there that doesn't involve just replacing it.
Now my CPU idles at ~35 usually, which is just 5 degrees above the ambient temperature (because of summer...), and hardly ever goes above 70 even under load, and still super quiet. Realize now I should have done the upgrade years ago.
Now if I could only get water cooling for the radiator/GPU I'm using. Unfortunately no water blocks available for it (yet) but can't wait to change that too, should have a huge impact as well.
