Mining Drill overheating on launch pad

[Rryk]

Hi,

I am trying to build my first ship for drilling ore and producing fuel on Minmus. Before I flew it to Minmus, I've decided to test it on the launch pad:

Unfortunately despite many solar panels that I expect to be used as radiators, and despite the engineer on board, the drill gets too hot and mining efficiency drops to mere 12%. What am I doing wrong?

The craft file is here: https://drive.google.com/open?id=0B9S8km6a08YmeUdrWkFzLVlOTk0

The game is KSP 1.2.2.1622 with the following mods:

I don't know much about the mods, but I know that solar panels aren't enough to cool down a large drill. Put a couple of medium thermal control systems instead. Extend them, then try again. Between them and your engineer, the overheating should stop.

As cubfan says, the solar panels will not cool a drill or converter.

Drills and converters create a special kind of heat called Core heat. It is the core heat that controls the efficiency level of the device. The only way to provide cooling for core heat is with either the fixed or the extendable radiator panels.
