I am trying to get back in the game. I have been running my 2 980's for a couple of days no problem. But today I started up some CPU task on prime grid and when running them my temp go straight to 100c. I had the cpu oced so I returned everything to stock and it still does it. I turned cpu use in Boinc down to 75% and it help but I still see spikes to 100c. I have a H100i on it that is around 4 years old idle temps are from 35c to 40c.
