I changed out the CPU block from the Optimus to the new EK Velocity 2.  I wanted to try that block out and see how it does.  Nothing was wrong with my Optimus, but I like the mounting of the EK one and it was really heavy since I got the nickel covered version.

Looks good. please let us know how that EK Velocity 2 CPU cooler performs compared to the Optimus (I have the Optimus V2).

What component(s) are you all using for monitoring flow rate? Bykski? Thermaltake? I've been considering adding one to my loop - currently I have a sensor for water temp and a cheap visual flow monitor only.

I use the Thermaltake Pacific inline Flow/Temp sensor.  It's pretty decent at around 60 bucks and it measures both flow and temp which is a plus.  It's more just to double check and make sure their is a decent amount of flow in the loop while add another thermal point that is measured.  I have a thermal plug in my pump/res combo that I used to display coolant info on my Aida 64 panel on my O11XL build earlier.  I still need to figure out my Aida 64 panel in my new build still.  I'm going to need to change the panel out for a smaller one since my current panel is too large.  
 
I'm also considering buying another case, make the plunge for the Corsair 1000D Obsidian.  It would make my build so much less complex and allow me to remove both slim 360mm rads and replace it with a medium 480mm instead.  I kinda like the idea of being so different with the Enthoo case but I'm not fully committed to it yet either.

Nereus, 
I didn't try to connect the thermaltake unit to the mobo.  It would require an addition piece of hardware and you have to run their software.  I didn't see the need for that to be added as it's a back up in case of something going wrong with the thermal plug I have in the pump/res combo.  It's hard to see, but I have a black thermal plug in the base of the unit which is connected directly to the mobo temp port.  I don't have a flow rate sensor plugged into my mobo at this time.  It's one of the things I would like to add, but usually you have to add another piece and run software for others as well to interface with the sensor.  
 
For my build, I didn't have a flow rate sensor so I wanted to run that thermaltake unit to meet my needs.  It's been working decently since I bought it last year and I have added one also to my son's build to keep track of his flow and temps in the loop for his pc.  
 
The 1000D case layout is just really large which should make the build so much easier.  Twin 480s in the front side by side and you can push/pull all the fans with a top mounted 360mm rad too.  I'm just not loving the price as Amazon wont ship it to me under prime and the local pc store I'm sure will ask for an arm, leg, and maybe the first born as well.

Beautiful system but 4 radiators, that is huge. I have an EK V2 on OC 12900k and KPE HC with 2 360s, I med and 1 thin and water temp is 29 stress testing at 23 ambient . Pump d5 distro plate @65%

I have 7 radiators in mine

The backside pic is 403 forbidden , I have a mp5 backplate cooler but I didn't use it for my current setup. Temperature was not that bad with stock pads, I tried the full coverage Optimus pad and it's too thick to effectively work with the stock backplate.

Good news is that my loops has been running leak free for 12+ hours. The bad news is that the flow rate is lower than I’d like. I’m getting only around 140 liters per hour. My system is pretty large with 2 * 360mm thin rads, 1 * 360mm medium thickness rad, and 1 * 480mm medium thickness rad. I’m running a single D5 pump res combo and was targeting around 170-200 liters per hour. Two of the rads are vertical so that should be impacting flow rate to a certain degree, but the loop other than that is pretty efficient imo with very little runs going back and forth vertically. I am running a mayhems stage 2 cleaning rotation now to see if I can gain back a few more liters but it doesn’t look like it will help. I’m thinking the velocity 2 block might be a it more restrictive than the Optimus block I had been running and I didn’t plan for that impact in my loop.

I might try and just run it like this and see how the temps will be. I think it will be fine at 120-150 liters per hour since I have so much rad capacity.

This might be fine, but I haven’t built a system with this much rad capacity yet so this is a first for me with 4 rads. This could be normal, but since this is my first 4 rad setup it’s been interesting to say the least.

probably worth adding a second pump. easy fix. my daily gets around 230-240 with 2x SR2 360 + 1x MO-RA3 360. 1 Laing D5 + 150mm res in case, 1 D5 Next + 200mm on mora. more rads are good but gotta keep it moving. worth considering

Zippy,
Thanks again for the info.  I looked at a bunch of options for adding another D5 pump to my loop and where it might fit without having to make major changes due to the info you added along with the numbers I'm looking at for flow with just distilled water.  I just ordered a EK FLT 80 D5 and based on the layout and the parts I have it should be able to be mounted a little above my bottom rad in a vertical position which would require only cutting the one tube and then putting the FLT 80 in-line there vertically.  It actually came out pretty balanced if I am able to place it there as far as the loop order.  That position will be pretty much in the middle of the loop order with my other D5 pump res at the start.  
 
My planned loop order will be:
 
Primary D5 pump/res combo - Vertical 480mm rad - Vertical 360mm rad - inline thermal sensor - horizontal 360mm rad - Secondary D5 FLT 80 - GPU Optimus Kingpin Block - EK Velocity 2 CPU Block - Top 360mm rad - inline flow/thermal sensor - return to primary D5 Pump/res combo. 
 
I could run into some clearance issues if I decide to vertically mount my gpu in the future, but I'll get around that when the time comes.  
 
The good thing about having this flow issue is that my Optimus block has been on extended water leak testing and so far no issues I can see.  I still haven't powered on the system yet though but I should be doing that sometime next week.  I might get the urge to just start the system up using the single D5 though.  This has been a long time coming and I don't want to add up the total cost on the things it took to get me to this point.   
 
Thanks again for the input on the flow rate.

How is your water temp that high? Prefer to run a super quiet fan curve?
Also thats 5.5 delta C, thats pretty damn good.
The EVGA block for me is around 23 delta C, about on par with what the aio did. Cant wait till i get my block to compare the three.
