**UPDATE**
After re applying thermal paste to my CPU, I no longer get temperature spikes on my CPU, Im still seeing 100% usage in my CPU from time to time in some games with GPU at basically 0 but temps stay below 70 c. I am going to chalk this up to the games I'm playing just displaying the wrong GPU usage because I doubt I'd be getting 100 plus FPS in Rise of the tomb raider @ 3440x1440p with below 20 per cent usage on my GPU.
