[Ed Stauffer]

Dark matter evaporates releasing heat or condenses absorbing heat. Thus you have clouds of hot gas surrounding galaxies which combine with gas and dust to rain back down on galaxies.

Extremely speculative that dark matter can emit or absorb "heat", at least in the form of photons. Remember, it is "dark". Other speculative theory is that it does not cool down because it cannot emit photons.
