Good evening, My PC i7 3770k had intermittent heat issues. Idle on a good day 15 C but would spike to 40c and games randomly crash. I decided to flush the loops and replace the water. The loop includes one cpu and 2 gpus. Since flushing and refilling the temps avg 60c idle but the gpus usually start off normal 45 c but will increase to 70c over time.
