overclocking reduce for 1080 = PL 70-80 mem 150-250 core 100-150, for 1070ti i don't know, i havn't this card.
for 1070ti try at 80% tdp. +135 +700
Or from the overclocking which is now done for -50 for the memory and -10 the core. Run and see how it will work, if we leave it steadily, if it takes off, then we reduce it, you can choose the thresholds yourself, I chose in step of 20
