Surface area of the fin stack matters. An air cooler will always be limited by the space available around the CPU. A water cooling radiator has more flexibility to be placed in around the case.

That said, having less than a 360mm AIO is probably a waste. Also, higher end Intel chips these days are so power hungry that they can't be physically cooled properly with the surface area available on the package.

Sure, but if you can find an air-cooled VW bus that's still running in this decade they're probably asking $30k for it.

My grandpa has a Vanagon but it's in kinda rough shape.

Body is pretty good but the interior is pretty much gone and it has electrical grimlins so it either starts and drives perfectly or just screams at you doesn't even attempt to start.

Super cool vehicle though.

And the ability to know where the heat is being dissipated too.

And get more surface area to the air than you could with straight air cooling.

And control the temperature more acurately if desired through a thermostat.

Porsche used to agree, until 1998.

It depends on which part of the environment the heat is being exchanged with - if your watercooling system is releasing heat to the ground under your house or a somebody else suggested (which is even more effective) a river next to your house, it's not at all equivalent to air cooling.

Further, the heat storage capacity of a material depends on both the kind of material and its mass, so almost all liquids have a higher heat sforage capacity per unit of volume than air (certainly water does) and solids even more (much more, given their much higher density) so even in the big scheme of things (i.e. were will most of that heat end up in given enough time), even heat released by a watercoolong system to the air will mostly end up in tne Earth's crust and oceans and only a tiny fraction of it will remain in the athmosphere.

Even if the water is used from a river, the heat still gets dissipated into the air from the surface of that river.

So river cooling is still just air cooling with extra steps.

[–] [email protected] 1 points 11 months ago

As I pointed out further down in my comment, solids and liquids have a much higher heat capacity than air (or in other words, they can absorb a lot more heat before they warm up), so most of the heat dissipated to the river would end up stored in the Earth's Crust and Oceans and very little of it in the Air.

It all makes its way into the cold vacuum of space eventually
