Yeah, back when I was into overclocking I looked at exotic methods such as chillers, thermo electric, and liquid submersion. The latter one was interesting way of building fully passive systems due to heat diffusion + lightning effects that looks amazing... the downside is weight and having your PC in the aquarium. With chillers / thermo electric, sizing is a problem because modern overclocked CPUs require monstrous amount of power, which means hugely overbuilt and noisy chillers. Thermo electric requires a lot of power + dedicated water cooling setup... was not really worth it for me.
