So I have a Alphacool Nexxxos XT45 420mm and EK coolstream XE 360 both on push pull at around 1300rpm. This so cooling my 7820x (4.7ghz) and 1080ti SLI over clocked. This is in my Thermaltake View 71 but I really want to get the Evolv X which would force me to use my 420mm push pull and a 280 slim in push only. For the slim I'd consider a nemesis GTS 280 which by my research would lose 70-100w compared to my 360. How much would this impact my temps in my current setup? Is a 420 and 280 slim adequate for my setup in the new Phanteks Evolv X case? Thanks!
