The issue is kind of on the other side, though: you can pay more to improve your cooling in a way that might be quieter or better; but, if you absolutely do not want any fan noise--nor any fragile mechanical motors to move air/water/oil/ether/whatever--you get to a point where money can't buy better cooling... you simply have to put up with less cooling, with less powerful chips that have lower thermal bounds and often simply aren't fast. Like, I don't buy a computer because it is fast, and as soon as a company starts telling me how fast their computer is I start bemoaning the lost battery life and certainty of a noisy active cooling solution that I don't want :(.
I recall a video from Gamers Nexus at a trade event, though only that it was sometime roughly within the last year.
Entirely passive (I THINK / recall there was no pump), heat based circulation, with just TONS of radiator surface and an unwieldy design. However for that entirely custom solution they could theoretically scale up with additional size.
Still, if someone's going _that_ overboard, the heat's getting dumped somewhere.
'Industrial Chilled Water' as in a connection to an external (to the room, maybe even building) pump, and an external cooler (usually evaporative cooling, could be mega radiators in the shade too) like you see at industrial sites.
