I have been struggling with ksp interstellar as the heat on say an antimatter reactor at 1.25m diamater produces 20,000 gw of heat and the only way to keep it cool is to have a graphene umbrella radiator at 40 meter tweak scale- i have tried everything in regards to proper installation and in game. i am sure that this is incorrect as i watch beucoupzero on YouTube (ksp interstellar craft builder) and watched him put two smallish graphene radiator wings with a 1.875 meter antimatter reactor and he has no problems. i have the same problem with the quantum singularity reactor and i honestly don't know if the temperature is meant to be this way or not. believe it or not i have been toiling with this same issue ever since i bought the game in 2017 . again i have tried everything from manual install with no other mods , i have tried ckan, and i eventually came to the conclusion that it was a glitch i could not fix and ended up giving up on the mod. (though i have still been trying every now and then) the forum is my only hope at this point. ANY HELP IS APPRECIATED. (+ i would attach an image but this is my first time using forum so i don't know how)
