you better put a recepi for cooling down lzh condesators in the game or i get really mad
And you'd do what, exactly? All of the items you get in the skyblock are coming from infinite resources, why even bother cooling down a lzh condensator when you can simply trash the old one in a void that's infinite and make yourself a few spares to reinsert whenever you need them? Getting really mad at the FTB content creators might get you banned, if they could even be bothered to trifle with you.
The whole point of this skyblock is to get to end-game content that's by far more insane than IC2 reactors ever was, what that can produce in power output is nothing compared to what you can build from Draconic Evolution and other end-game mods.
If you want to blow your skyblock base up with some reactor design that might be unsafe, that's your business. I would, however, suggest you build it in a section of it's own, far away from anything you want to keep, which would be most of the equipment that costs a lot of resources to get, and your spawn point for the map.
