Ofcourse...
Let GPU fans at 100% with temptarget 60C is definitively bad idea...
80C with fans at 80% is way better...
Both are bad. I prefer 50-60 degrees with 50-65% fans
agree here, anything more then 75 degrees keeps me nervous, so I'm trying to keep below 70C
of course the temperatures are depending on algo, that is why lyra2z and phi are my favourites
