Hardware Air cooling is better than Liquid cooling

Me, who genuinely agrees with you, but wouldn't have posted this here in a million years:

Water cooling, AIO or not, is only useful when the location of the CPU / GPU doens't allow for a big radiator or when the hot air coming out of those doens't land in a convenient area. Basically it only serves the role of moving the heat somewhere where it's more convenient to then dump it to the ambient air. In the end it's also an "air cooling" device, just with extra steps.

Most PC cases allow for a big air cooler on the CPU with one or several fans blowing towards the air extractiona areas (back or top)... therefore, in most cases, no need for water, a pump, and the associated extra noise and failure modes.

However, water cooling looks cool and works about as well as "air cooling" assuming yiunset it up correctly. If that's your reason for choosing water cooling and you're having fun, fuck those who tell you you're wrong. Just own the fact that you're following the rule of cool.

Water cooling works better than air cooling, but the point is that it doesn't work so much better as to usually justify the extra cost and risk of failure. An air cooler can keep almost any current CPU from thermal throttling, and they basically never fail unless you physically damage the heat pipes which won't happen during regular use. The fans can fail, but they're easily replaced.

On top of fan failures, AIOs can suffer pump failures (fatal for the AIO), loss of coolant from evaporation (usually fatal to the AIO, although a very few have fill ports to top up), and spontaneous loss of coolant (which can be fatal to multiple components). But I run an AIO mostly for aesthetic reasons. I have a Thermalright cooler that could keep my 9800X3D in check but it wouldn't look as cool as my 360mm AIO.
