temperature is analogous to surface gravity which gets weaker at the event horizon as the black hole grows.

temperature is not expectation of a kinetic energy distribution of micro constituents. you don't measure a black holes temperature with a thermometer because you can't get information out of a black hole

Doesn't a black hole radiate hawking radiation and a smaller black hole radiate with a higher temperature than a bigger one?
Yup wikipedia agrees, temperature is inversely proportional to mass. Surface gravity as well.
