Custom loop watercooling (not the all in one kind) and especially, direct die (delidded) cooling, can just about tame the beast. Someone has linked the DerBauer vid where he does it.

Of course, the market for enthusiast stuff like direct die watercooling and KS-series purchasers have a significant overlap <:o)

I don't think aircooling is going to do it for these – though even watercooling can become loud if stressed. I guess phase-change heat pumps are the logical next step. Peltier cooling is of course totally silent, and enthusiasts dabbled on it already back in the 90s – not sure how common it's these days outside astrophoto imaging rigs. But you can fairly easily get temperature deltas of around 100 kelvin with a Peltier heat pump. You'd still have to dissipate the heat somehow, of course.
