I am running the Corsair H115i RGB kit. My 9700K at 5 ghz doesn't go over 60°C, solid AIO cooler. I'm sure the Soldered chip design helps too.
Also, RAM speed helps FPS too. When I built my new machine, I forgot to set the XMP profile and the RAM was stuck at 2133. When I enabled it, I jumped up 5 FPS (at least) just in that adjustment alone. I then did the overclock and got even more FPS out of DCS.
