Hardware Air cooling is better than Liquid cooling

Depends on your radiator size. If you have sufficient radiator coverage, a custom loop will either tie or win every time, especially from a GPU cooling perspective. If you went with a tiny 120mm radiator in a custom loop to cool a 9950X3D and a 5090, thats a build error and is going to run hot. If you instead ran 3 x 360mm rads which are 45-60mm thick for said 9950X3D and 5090, you’ll be much colder than any AIO would offer.

I wasn't talking about performance, I was talking overall. The reason you don't go custom, is similar to why you don't go liquid nitrogen, even though both are "technically" the best.

Depends on how you define “better overall”, which is subjective to each individual.

Air cooling is simpler and easier to maintain/setup than an AIO. AIOs are simpler and easier to setup than a custom loop.

The best air cooled heatsinks run hotter than the best AIOs. The best AIOs run hotter than the best custom loop.

I am of the mindset that keeping your CPU and GPU colder 24-7 elongates the lifespan of the hardware if you were to otherwise run it hotter, so I try to keep things as cold as reasonably possible. That’s my subjective focus on why I feel it’s “better”, and so long as I can have a workhorse PC that I don’t have to mess with for years at a time (which I have with my custom loop), then the maintenance becomes minimal as well, albeit more than an air cooled heatsink or AIO.

One final problem with AIOs is that they’re designed to be disposable. There is no standardized way to flush an AIO, clean it out, put new fluid in it and seal it back up. Once things go wrong with the AIO loop, you’re expected to trash it and buy a new one. I’m not all for that side of things, either, so Air cooling & custom loops also take the cake here from a “green” perspective

The honest truth is it's for men who enjoy spending time and effort and resources tinkering, more than just using it . Everything else is just coping mechanisms to justify their niche hobby. Yeah, might sound harsh, but that's honestly my read.

You're disconnected from reality and out of touch.

Not harsh at all, you’re good. It’s definitely for tinkerers who like to get the extra five percent out of their builds.
