The 730T supports 360mm rad in top, but you will be into top drive bay.
A 360mm AIO cooler will be one of the best cooling solutions for 4790K,.. if it is adequate @ 5.0Ghz overclock depends on Vcore, ambient air temp, and CPU load,.. you will need to test and see what results you get.
You will want to connect water pump as per instructions,.. most likely to 12V CPU fan header.
If you have Arctic MX-4 on hand,.. I would use it. Otherwise the pre-applied TP would be fine.
For best results and less stress on your hardware,.. click Finnish on your CPU slot, and when finished with current WU go into Configure and remove CPU slot,.. then Add a few flags for GPU slot,.. next-unit-percentage 100, and client-type advanced. Then slide folding power up to Full,.. set check points up to max all the way to right which I think is 30-min.
It's not worth 3000 PPD running your CPU @ 100% generating all the heat/stress,.. next-unit-percentage 100 flag will only allow download of next WU after current WU is at 100%,.. your time TPF, ETA and PPD are based on time which starts the second WU is downloaded,.. and client-type advanced pays more points then reg work units,.. the beta work units pay highest PPD but can cause issues if your not monitoring your rig.
Most folks that did not vote for Trump will be proud to call him there President, after his first six months in office,.. they will see that Donald is not a politician and actions speak louder than words.
