130F / 55C is usually reckoned as the minimum useful temperature to kill most nasty stuff off. Need 10 hours at that temperature to cook most seeds dead. See
Hot Composting, Accelerated Composting, Thermal Composting
But if you succeed in getting to that temperature, you'll probably need to turn it daily or it will get too hot.
