In sum of the below; you will want to hang around 140 - 160° F; that way you will be above the minimum range of thermophobic parasites and below the temperature that affects thermophilic bacteria (who are doing all the work). How hot it can get depends on your set up and climate and other variables, but managing it is a pretty active and important aspect of the process.
From some information from Washington State University-
I am not sure if you are worried about the temperature, however in terms of safety bear in mind the following:
Eggs of parasites, cysts and flies have survived in compost stacks for days when the temperature in the interior of the stack is around 135° F. Since a higher temperature can be readily maintained during a large part of the active composting period, all the material should be subjected to a temperature of at least 150° F for safety.
In terms of the temperature dynamics of the compost:
Experience shows that turning to release the heat of compost piles, which have become so hot (170°-180° F.) that bacterial activity is inhibited, is not very effective. When the material is actively decomposing, the temperature, which falls slightly during turning, will return to the previous level in two or three hours. Also, it is impossible to bring about any significant drop in temperature by watering the material without water logging the mass... Variations in moisture content between 30% and 75% have little effect on the maximum temperature in the interior of the pile. The initial temperature rises a little more rapidly when the moisture content is 30% to 50% than when it is 70%... Deeper piles caused higher temperatures and better temperature distribution, and subject more material to a high temperature at any one time. Hence, the actual mass of the material evolving heat is important in providing adequately high temperatures*.
