Rereading Hawking, the temperature of a black hole is inversely related to its mass, so small black holes produce more HR and lose mass faster.
Eventually the mass of the BH would reduce to a point where "... the most reasonable guess is that it would disappear completely in a tremendous final burst of emission, equivalent to the explosion of millions of H-bombs."
If DM was actually small BH, would we expect to observe a few of these explosions, or is the universe not old enough yet?
