First, the ability to remove large volumes of heat from a DC (or analogous plant) is largely dependent on the local geography/environment. In modest cases, that may come down to average ambient temperatures and the cost of electricity. In more extreme cases, access to a massive heat sink such as a body of water may be necessary.
Second, the technology used to evacuate heat is very mature. The modern world depends on HVAC and has for a very long time. While there are incremental advances such as new refrigerants and compressor technology, there is always a cost to performance tradeoff.
Note that the theoretical limit on cooling performance (CoP) of a Carnot engine is ~7.8. Check out this report by the IEA (page 43) https://iea.blob.core.windows.net/assets/0bb45525-277f-4c9c-...
