Ryzen 7 1700 is overclocked to 3.85 GHz. The Kraken x52 keeps it fairly cool down to about 55 degrees at full load. This would probably be improved if the Phanteks P400S supported a radiator mounted at the top (it only supports rads mounted at the front). I wish I had bought an x62 to take advantage of the 140mm width of the case.
I should have gone for an OC'd memory build since the Gaming K7 supports up to 3600 MHz. I wussed out and went with the highest non-OC ram speed at 2666 MHz.
Overall, I love the case. The tempered glass and clean front looks classy as hell. The ambient red LED has a really nice effect. The case's fan controller lets me keep things running super-silent when I don't need as much airflow, then crank it when I want some performance.
