The NT-H1 paste is pretty good to be fair I have used AS5 and Tuniq TX-3 in the past and the NT-H1 is just as good as those if not better by about 1-2c. It takes about a day to cure and there isn't really anything you can do to speed it up, the longer it takes to cure the better really.
I have my CPU running 100% load 24/7 with my D14 using the NH-T1 paste and my temps are around 55c and on a really hot day 57-59c and that's with both fans in silent mode.
