1070 ti pulling 480 sol/s isn't pushing hard at all.
70C though is high on temp for 115 watts, especially with 80% fan - SOMETHING is blocking airflow to the cards or the room is VERY VERY hot.
Those Aero blower cards shouldn't have THAT bad of cooling, though they would tend to run a LITTLE warmer than good fan-cooled cards unless they're in a case.
My EVGA and Zotac 1070 ti cards in my "new shelf/rack" first rig only run 62-63C at 50% fan in a room that is 86 F measured right above the "room fan" that blows air into that rig.
It's POSSIBLE that you got a batch of flaky cards - but if they're working for video playing it sounds more like you're pushing them too hard, probably on the memory clock.
What are your settings if you don't mind asking? I think the main problem is on the USB stick, and it was the reason that system crashed and not the OC speeds. Even if for sure i was pushing the MC way over what needed.
Do you recommend anything to remote monitor the rig using nvOC? I think i will end up using teamviwer but was looking for other alternatives
simplemining is 2 usd a rig a month uses linux allows clocking and monitoring. If you have bigger rigs 2 usd a month is cheap enough.
I like nvoc but it is not as good as simplemining for maintaining multiple rigs in multiple locations.
Still doing some setup work for winter mining. But I have 3 simple mining accounts with 13 rigs in all So I pay 26 usd a month but the rigs earn 3000 usd a month
so under 1 % it is worth it to me.
I will be setting up a 4th location much larger it is 1 hour and 10 minutes from my house.
Simple mining will earn its keep as that spot will have a lot of rigs and I do not feel like driving to change shit more then 1 time a week.
