Good Custom Loop for Enthoo Pro M TG?

[Norrixisanerd]

So Lads, third post...eyyyy i guess
So I originally was supposed to get a 3800x, but I was gifted a 3900x that I can over clock pretty well (4.6 all cores) the problem is my 360 aio died and I was gonna buy a 360mm cooler but then i felt like I wanted to start exploring the exotic, and since I am an aesthetics nerd, I want to do it in my Phanteks enthoo pro m TG black on white edition with White LED QL's on a black frame, the problem is now, that I don't know any of the good cooling brands and I don't want to just buy a kit and get done with it. I would like to keep the aesthetics but I also want good performance and I've been hearing a lot about Hardware Labs and Optimus cooling (Optimus is WAYYY out of my budget....) I have a budget of around 400-600 US btw but I've heard that isn't that much...
I NEED TO PAY FOR MY FOOD. OK!?!?

Little bit more about it: 

• Just the CPU for now
• I do know that I need Radiator cleaner 
• you're gonna be recommending it to a guy who literally is clumsy.
• System is (not listed on my profile need to fix) MSI MEG ACE, 32gb 3600 Gskill Neo, 2 Nvme Drives, 1 ssd, 2 hdd, Dark Pro 11 850w semi modular 80+ Platinum powersupply, MSI 2070 Gaming 8G (That cannot be liquid cooled for some weird reason)

but if anyone can like idk, help me out on this and set me up with a cool system that would be great! If no aesthetics then that's fine.
 

ANY suggestions IS APPRECIATED!
