It's crazy how sensitive the 5800X is in terms of cooling and the impact on performance. I started with the Wraith Stealth cooler, then on to the beefier Wraith Prism cooler, then got the Phanteks glacier 360 AIO, then upgraded to the new Phanteks Enthoo Luxe case with better airflow and each and every time there were significant improvements in both the temperature (5 - 10 degrees) and subsequent performance of the CPU. Even adding an additional exhausting fan at the back a couple of days ago gave me an improvement in temps and cpu benchmark scores.
