It's an HP OEM (because I moved countries during the pandemic and getting parts where I settled was ridiculously more expensive).

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).

I bought my current gaming desktop off a friend as he didn't need it anymore when I was looking for an upgrade. It had an AIO cooler. The pump made so much noise and it seemed like I had to fiddle with fan profiles forever to get it to have sane cooling. I swapped it for a $30 CoolerMaster Hyper 212 and a Noctua case fan. It cools well enough for the CPU to stay above stock speeds pretty much all the time and is much quieter than the AIO cooler was. I'm not suggesting this CPU cooler is the best one out there, but just pointing out its not like one needs to spend $100+ on a cooler to get pretty good performance.

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.

Honestly at this point it's not so much about money as it is about whether or not this particular case/setup/components combo is salvageable with minimal effort.

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.

Depending on the fans it may be possible to re-oil the bearings.

Interesting idea. I feel like the fan noise from my GPU is just air moving, but maybe not.
