First water loop issues
First water loop issues
Well, here are a few suggestions to address some issues in this loop:
1. Three reservoirs seem unnecessary—they offer no real practical or cooling advantage and actually increase flow restriction because of many extra 90-degree turns. Consider an alternative solution if that’s your reason for including them.
2. Link the GPU blocks in parallel—both connectors should connect, using the port nearer the outputs and the other for the inputs.
3. Prevent long back-and-forth runs by directly connecting the GPU blocks to the CPU block; the order doesn’t matter.
4. On the radiators, set the lower port as an inlet and the upper port as an outlet.
Implementing these changes will significantly improve loop flow, making it easier to remove air from the system and enabling the pump to run at a lower speed, which reduces noise.
It requires a large amount of piping and turns for one pump to transport water.
I would've arranged this on separate loops—one for GPUs and another for CPU/RAM/MB. The main reason was that the GPUs would generate a lot of heat during gaming, and if their heat directly impacts the cooling of your CPU and other parts, you might not achieve the performance you expected. This also significantly limits the room for overclocking, and the overall setup would require less tubing for each pump to move fluid efficiently.
This is my workstation/gaming build.

I have a lot of 90' angles like you do, but having the tubing distributed really does affect how each D5 performs. Of course, both pumps are placed at the base of their reservoirs and run by gravity. This puts a lot of strain on them, causing wear and tear, so I strongly suggest adding some elevation between the pumps and reservoirs. Placing the GPUs in parallel also helps reduce pressure. Although there isn’t a major cooling advantage, it does ease the workload on the pumps.
I’d lean toward supporting both rubix_1011 and nons3ns3s. But if you’re aiming to maintain the look of your current setup, just running GPUs in parallel and adding another D5 pump should suffice. Still, dividing into separate loops would remain the best approach.
Tubing and bends likely perform better than expected, you're correct. Reservoirs are noted only because they introduce at least 6-90 bends, which result in a flow rate reduction of about 10-15% (roughly 2-3% per 90 bend/fitting).
P.S.
I believe I've reached the final stage of my "less is more" project. Here are the links:

Remaining tasks (time required):
1. Fix pump and res.
2. Replace tubes with glass.
3. Swap side panel window for a slightly tinted TG.
