This is almost identical to an issue I was having with my 680 - idle temps of around 70 showing 0% gpu usage. I even posted a topic here titled something like unusual overheating issue. I fixed mine after a lot of trial and error by installing new nvidia driver via a custom install option as a completely new install replacing any prior settings.
I have a strong hunch this is a virus or software issue for the topic creator and that replacing thermal paste won't improve anything. I think it's an advanced bitcoin virus that falsely shows 0% gpu usage to divert people's attention from it.
Anyway my pc is back to normal now and I did'nt have to reinstall windows or apply thermal paste. My advice is to run malwarebytes and unistall any gpu drivers completely before trying a clean install of the drivers to see if that helps at all.
I've tried to run Malwarebytes and it came up with nothing, I'm going to try the thermal paste first...if that doesn't help I will just do a fresh install.
Thanks again.
Edit: Ok just finished getting the card put back together with new paste on, It's now idling at 50c ish...
Massive improvement in my opinion...
Anything else I can do?
