Low part count cooling for LV-Ns?

[Frozen_Heart]

I'm wondering has anyone found a way of cooling LV-Ns without adding too many parts? I've seen plenty of solutions that add 10 or more parts to each engine but my PC struggles as is so this isn't an option.

You can use solar panels, they act as radiators

Solars and the engine preecooler are best bets. the preecooler can both store ALOT of heat/radiates well, and solars act as very good radiators period.

Ive tried both precoolers and solars.

But just use long mk2 liquid tanks, or if you only have one nuclear engine, a short mk3 liquid tank. If 10 minutes is enough to burn.
