I just built a new system, specs below.
The MSI MPG's are a nice series. I have the Gaming Pro Carbon, 32 gb of Gskill trident RGB RAM.
I purchased a Corsair H115i Pro, and with the 9700K overclocked to 5 ghz, my temps barely hit 60*C. Its extremely fast and boosted my DCS performance WAY UP. Next on the to do list is a better GPU. Also, the MSI board has an easy overclock one touch button, going with a water cooler like that, you wont burn up your CPU.
