I put thermal paste on mine and the heat sink is running 70 C.  Junction temperature is probably 85-90 C, which is hot.  But as-mentioned it is within spec so it should last a while.  Cheap part so failure would only be an inconvenience.  I am going to reorient the regulator so the heat sink fins are vertical for a little better convection.
