Is this with vents in the reactor too? There isn't any natural passive cooling from a reactor so they will hold their heat without anything actively removing it.

First, than you for your fast reply.
Yes, i used 1-2 single Uranium cells with advanced heat vents, component heat exchanger and lzh condensator. I don't know if this is relevant, but i updated the mod from 2.8.105-ex112 to the latest release version.
Yesterday evening i replaced the lzh with overclocked heat vents, since that the reactor is at 0% heat. Is that common?

I hope that the information i have provided is useful for you. If i should make any Test, just say it.

It seems that you are new to IC2, but I don't think that is a bug. Advanced heat vents don't pull heat from the reactor, since you put it next to the fuel rod, it draws heat from the fuel rod when the reactor is on. Overclocked heat vents, however, pulls 36 heat from the reactor and vents 20, so you see it cooling off.
Please refer to and for more details.
