Not only would the latter have slightly more relative heat capacity, but more importantly they would be able to give off their heat 10x more efficiently (greater total area). | |

I mean, your room would get chilly for a few minutes, but nothing catastrophic is going to happen unless you insist on cuddling up to it and that will hurt enough to convince you not to. | |

Heat capacity near absolute zero is very small (approaching zero), which means that cooling down an object ever further doesn't do much, at all, in terms of the heat that it can absorb. At most, tho cold would freeze your skin, if you were to touch it... which would be foolish, painful and perfectly survivable. | |
