I have a Gigabyte Z390 motherboard, an i7 9700K, a Corsair H115i, an EVGA 1060, etc. that I plan to fit into a Corsair 300R case. Does the following sound right? Put radiator in two front holes with air sucking in. Have top rear fan exhaust and somehow tied to speed of two fans on radiator. I plan to block off other fan holes (on top, bottom, and side). Or do I need more exhaust fans?
