Whats wrong with this radiator

[Iso-Polaris]

This is the thermal image of my station in minmus orbit

The radiator is overheating itself to arount 950K, and none of my vessel part is generating heat.

Why !!!!!!!!!!!!!!!!!!!!!!!!!!!!?????????????????

The radiator(s) will draw heat from your entire vessel to themselves, and try to dissipate it, until your vessel is at a certain temperature.

The radiators are also "smart" -- they draw in all the heat they can until they are just below their limit, and then stop. So in a static situation, even if they are glowing red, you don't need to worry about them -- they won't heatsplode.
