A cooling apparatus and method comprising a heat exchanger in thermal communication with a plurality of computing devices, a single or plurality of filtered coolant intake pipes and corresponding coolant exhaust pipes in thermal communication with the heat exchanger via a configurable filtration unit. The apparatus and method includes a geothermal heat sink comprised in a geothermal field, structured to transport heat away from the heat exchanger via the filtered coolant intake and exhaust pipes, and a coolant pump operatively coupled to the coolant intake and coolant exhaust pipes in a coolant circuit and configured to transport heat absorbed by the heat exchanger to the geological heat sink comprised in the geothermal field.
