I don't think the issue of small black holes matters to BotNS - the black
hole described is absorbtive, and thus large enough to have a low
temperature. In the context of black holes, there's actually not much
margin between the temperature of a stellar interior and that of outer
space. They are either colder or hotter than either, and those that persist
are certainly colder.
