I think many miners run their rigs cooler with a lower tdp. and lower hashrates.
Anyway, Signatum #7 released yesterday should be faster than #6..
TDP 80 ,.CC +150 All GPU under 70
https://ibb.co/mCXTRaSignatum sp-mod #7 does 41.8 on the 1080 with +75 on the coreclock
For 10 seconds may be

then crash or slow down. I can get 43 for 1 or 2 minutes from CWI. And can get 42.5 for half an hour or more. But than it will crash
for example. TDP100 +100CC for first GPU and voula 42.5:
https://ibb.co/dG2pXFP.S. Why people speak about OC without connection to final CC. I have 4 types of 1080. All have much different base CC, so +250 for one is the same as +80 for another
