The hottest the incubator got was I believe 90 or 91 and that was due to us not turning on the AC on a hot day and the whole house got a little warm. Other than that day it has stayed between 86-87. The other clutch was laid only a few days after this one and it never experienced dehydration issues. So far all of the babies appear healthy and not kinked (only one has hatched so far. Still waiting on 3 to hatch).
The reason I think dehydration was the issue is because the normal that is still left to hatch from this clutch was located right in the middle of the egg tub. During the dehydration issue there was still a little dampness to the vermiculite around his egg and his egg barely dimpled. From what I can tell, he does not appear kinked. We'll have to wait and see what he looks like when he comes out.
