That's the high end crested gecko eggs should be incubated at..anything over 82 will likely kill the eggs. 83F is the maximum incubation temp. Since you are incubating at 80-82F it will take about 60 days for them to hatch. They can hatch fine at room temperature, between 68-75F fine. I incubated at room temperature which ranged between 72-76F which took about 65-70 days to hatch.
