Also, the de Havilland dash8 has sheilding on the fuselage to protect it from ice being thrown from the props. I believe that the dash 8 uses an anti-icing system. With these two thoughts in mind, I would say that the blade temperature would be pretty low. Probably ambient temperature. Remember, the bigger the prop, the slower they turn. No heating up the surfaces from friction heating.
