I'm not a fan of the type of 90's you have in some locations, particularly the in and out of the GPU bridge.
One thing that you can't see externally, but need to watch for as you build, particularly if you're using fittings from multiple sources, is that some are absolute disasters as far as flow capability . . .
In the pic below, the 45 on the left is a Bitspower, the 45 on the right is some other POS brand, and the M to F rotary in the middle is also some POS brand.
Look at the bore diameters . . . compared to the Bitspower, the others might as well be pinholes.
Just one POS fitting like those two, can trash the flow for the whole loop.Warning: Spoiler! (Click to show)
The other thing to watch for as you build, is that some fittings have a longer male thread than others, and some fittings have a very short female thread, that if you use a long male thread into it, can restrict the flow markedly. . . . FC Terminals on GPU blocks would be an obvious example, but surely isn't the only example.Warning: Spoiler! (Click to show)
Tearing everything down to inspect stuff is probably the last thing you want to do, but if you fail to get acceptable temp results, you may have to just bite the bullet.
Told you the back was a disaster
temporary but still cringe worthy overall.
The most I did was check practically every fitting since I swapped things around, I'll only be able to clean inside the gpu block when I get new cards or install the rigid tubing, I'll get rid of the terminal and go parallel at that point.
Safe to say I'd need 2 pumps in each loop to run at the optimal level, even when I tidy things up and install the rigid tubing, there is going to be a lot of restriction because of the runs and aesthetics, but at that point pump speed won't matter

Maybe on stock settings temps would probably be a bit lower
You have 10 posts per page don't you?
There is like a dozen posts of me, I do not have a flow meter, loop is temporary, definitely right about the loop though, I need to tear it apart.
This is more of my fault guys, I appreciate you all helping me try to troubleshoot and/or think outside the box. Since I've been putting off the upgrade on the tubing and video cards(not by choice) I keep trying to rule out that nothing is clogging cpu or gpu block and for all I know a fitting could of flaked up and easily started a nice nest inside the microchannels. I will go back and +rep you all for taking the time to help me.
Edit - Just gave it another spin, stock bios the water won't break 37.5C sucks I can't test parallel on one pump before eventually tearing it all down
