165F = 74C which is the temperature necessary to kill bacteria in the meat. If you heated the meat to 165C it would be completely dried out as the water in the meat would prevent it getting above 100C.
I would serve it cold as reheated turkey tastes....reheated unless you make a stew or curry.
That's what I suspected Danny, an oven temperature of 165C would do the job for a carcasse after about 20 mins. Fortunately there is no danger as the turkey was only cooked a day before. :-)
