Template:Stats table Core Cooling
To maintain an active drill or converter core at optimal thermal efficiency, radiators must provide enough unused Core Heat Transfer capacity to fulfil the "Required Cooling" stat, shown below:
|Image||Part||Required Cooling (kW)||Max Cooling(kW)|
|'Drill-O-Matic Junior' Mining Excavator||50||50|
|'Drill-O-Matic' Mining Excavator||100||100|
(*) The Convert-O-Tron 125 is a special case - it can not be maintained at optimal thermal efficiency because its "Max cooling" cap of 50kW is below it's required cooling (100kW). With the help of radiators, it will still reach equilibrium, albeit a little hotter than the optimal 1000K. This is possible because core heat production scales down at higher core temperatures, as the thermal efficiency drops off.
Also note, for both Converters, that the required cooling figure is per active conversion mode, with each unit able to have any, or all, of their four ore conversion modes active at the same time. Hence the Convert-O-Tron 250's required cooling can also exceed its maximum permitted (e.g. 3 modes will produce 600kW of core heating).
