I thought, somebody asked how much is a nanokelvin or something like that.

About low temperature in BH. Temperature is relative motion of particles, so you have to have at least two of them to have temperature. Well, in BH we have a singularity, so ho do you define temperature of singularity? If there are no parts in singularity - no temperature can be assigned to it. But if a singularity consists, for example, of something oscillating/rotating, then you can define at least energy E of this oscillation/rotation and then speculate about possible "temperature" of that motion defining it conventionally as T=2E/3k.

This way you'll probably get extremely high energy/temperature of BH core.
