 Select a cooler based on the BTU/hr derived in step 1 above.  For the case of the 50 hp Power Cube, search for coolers that dissipate between 31775 and 38130 BTU/hr.  Vendors list cooler specs with heat dissipation and Gallons/Min or Liters/Min.

   Note: The "COOLING BTU / HR" ratings is with 2500 cubic-ft/min airflow and 100°F differential in oil and air temperatures.
