I really doubt liquid is easier for a data center. They have airflow solved pretty well and noise doesn’t really matter. Liquid failing could potentially do way more damage, and might require shutting down whole areas for repair/damage prevention in the case of a single leak.

If they did do liquid at scale, it wouldn’t be done in a way it would work down to consumers. It would be like custom boards with full coverage blocks for the whole system that tied into whole room water chillers or something.
