1. A method of controlling a high density liquid cooling system to liquid cool components, the method comprising:
measuring a first temperature at least one of at an inlet port or at a first point in a primary coolant loop;
measuring a second temperature at least one of at an outlet port or at a second point in a secondary coolant loop;
determining a temperature difference between the first temperature and the second temperature;
calculating a heat transfer efficiency of a heat exchanger based on the temperature difference; and
calculating a total heat rejection value based on the heat transfer efficiency, the total heat rejection value representing heat rejected from the secondary coolant loop to the primary coolant loop.
