They mostly don't, but this is also not how the datacenters cool them.

A datacenter will either have an open water loop, or an all in one taking heat to a more advantagous place for a radiator to be, or at the very least better managed airflow with bigger fans and more specific air baffles.

This thing has no such luxury and has a small area and unknown broader thermal context, so screaming it is to make up for the limitations of the scenario.
